How do you find the base of a cylinder?
Answers
Answer:
A cylinder is a solid figure with two parallel circles of the same size at the top and bottom. The top and bottom of a cylinder are called the bases. The height h of a cylinder is the distance between the two bases.
Step-by-step explanation:
Formula: Since the base of a cylinder is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.
±√121 what is the answer
Answers
Answer:
±√121 = ±11 (11, -11)
Step-by-step explanation:
1.First, find two equal numbers multiplied by each other to get 121:
This will be 11×11, so the answer for the square root is +11 or -11.
2. Or you can find the square root of a number using this method:
draw a line splitting two sides from each other.then, write the number inside the square root on the left side of the line.after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).write the answer to the division on the left side of the line.next, rewrite the two steps above by writing a number that can be divided by the answer of the division.stop writing the number when you get to number one on the left and right sides.finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.you can understand it more from the picture below, I also did another example for this method.find the area of a non shaded area

Step-by-step explanation:
The scale drawing has width 8 in. and length 12 in.
The scale is 1 in. = 1.5 ft
To find the real linear dimensions, multiply the scale dimension by 1.5 and change from inches to feet.
The real width is 8 * 1.5 ft = 12 ft
The real length is 12 * 1.5 ft = 18 ft
The scale area is 8 in. * 12 in. = 96 sq in.
The real area is 12 ft * 18 ft = 216 sq ft
The scale perimeter is 2(8 in. + 12 in.) = 40 in.
The real perimeter is 2(12 ft + 18 ft) = 60 ft
Now we look at the statements.
A) True
B) True

. A solid metal cylinder of radius 5 cm and height 12 cm is melted down and recast into a
cone of base radius 10 cm.
Calculate the height of the cone.
Answers
Answer:
H = 9 cm
Step-by-step explanation:
The volume of the cylinder equal the volume
[tex]\pi\: \: {r}^{2} \times hcy = \frac{1}{3} \pi {r}^{2} \times hco \\ hco = 9 \: cm[/tex]
The height of the cone is 9 cm.
The volume of the cylinder = The volume of the Cone
This is because the exact metal cylinder was recast into a cone.
Volume of a cylinder:volume = πr²h
r = 5 cm
h = 12 cm
volume = π × 5² × 12
volume = π × 25 × 12
volume = 300π
Volume of a cone:volume = 1 / 3 πr²h
r = 10 cm
h = ?
300π = 1 / 3 × π × 10² × h
300π = 100πh / 3
900π = 100πh
h = 900π / 100π
h = 9 cm

12. A logo is designed that has four pink circles within a white square.
The square has side length 16cm.
Find the area of the logo that is white.
Answers
The white area of the square is equal to 55.04cm²
How to calculate the white area of the square?To calculate the white area of the square we must perform the following operations.
Calculate the total area of the squareTo calculate the total area of the square, we multiply the side length by the base.
16cm × 16cm = 256cm²Then we must calculate the area of the pink circles, for this we use the following formula:
A = Π × r²Then we proceed to replace the values of the number pi and the radius:
A = 3.14 × 4²A = 3.14 x 16A = 50.24cm²Now we multiply the area of the circle by four to find the total area occupied by the four circles inside the square.
50.24cm² × 4 = 200.96cm²
Finally we subtract the area of the 4 circles from the total area of the square and the result will be equivalent to the white area of the square.
256cm² - 200.94cm² = 55.04cm²

The complete table of the values for the equation y = 4x + 9 is;

What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation is,
⇒ y = 4x + 9
Now,
Solve the equation for the values of x as;
The given values for x are;
x = - 2, - 1, 0 , 1 , 2
So, Find the value of y as;
Substitute x = - 2 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × - 2 + 9
⇒ y = - 8 + 9
⇒ y = 1
Substitute x = - in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × - 1 + 9
⇒ y = - 4 + 9
⇒ y = 5
Substitute x = 0 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 0 + 9
⇒ y = 0 + 9
⇒ y = 9
Substitute x = 1 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 1 + 9
⇒ y = 4 + 9
⇒ y = 13
Substitute x = 2 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 2 + 9
⇒ y = 8 + 9
⇒ y = 17
Thus, The complete table of the values for the equation y = 4x + 9 is;
x - 2 - 1 0 1 2
