The area of a sector of a given circle is 37.7 m².
Given that, the radius of a circle=4 m and the central angle of a circle=270°.
What is the formula to find the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector is θ/360°(πr²).
Where r is the radius of the circle and θ is the angle of the sector.
Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².
Therefore, the area of a sector of a given circle is 37.7 m².

Which system of equations could be represented by the graph?
which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?
Hi there!
[tex]\large\boxed{\text{Center: (7,2); radius =} \sqrt{10}}}[/tex]
We know that the standard form of the graph of a circle is:
(x - h)² + (y - k)² = r²
Where:
h = x-coordinate of center
k = y-coordinate of center
r = radius
We can identify the following from the given equation:
(x - 7)² ⇒ h = 7
(y - 2)² ⇒ k = 2
r² = 10 ⇒ r = √10

Explain how you went about finding a solution to the problem. We want to go to zoo. 7 adult tickets and 7 kids tickets equal 50 dollars. Adult tickets are twice as expensive as the kid’s ticket. How much do the tickets cost?
Answer:
Cost of Kid's tickets =16.66
Cost of Adult's ticket =33.34
Step-by-step explanation:
Adult Tickets=7
Kids Tickets=7
Both total = 50$
So 14 tickets =50$
Now: Lets the cost of kid's ticket=x
The Cost of Adult's tickets be 2x
=so (x+2x)=50$
=3x=50$
=x=16.67 for 7tickets
Cost of Kid's tickets =16.66
Cost of Adult's ticket =33.34

Find the solution to the following system using substitution or elimination:
Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.

Rewrite –220° in radians. Write the solution as a fraction in simplest form.
Answer:
- [tex]\frac{11\pi }{9}[/tex]
Step-by-step explanation:
To convert degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex] , then
radian measure = - 220 × [tex]\frac{\pi }{180}[/tex] ( divide 220 and 180 by 20 )
= - [tex]\frac{11\pi }{9}[/tex]

Answer:
a = 9
Step-by-step explanation:
For solve the problem we can use the Pythagorean theorem in this way
a^2 + (3√3)^2 = (6√3)^2
If we solve the equation we have
a^2 + 27 = 108
a^2 = 81
a = +/-9
we take only the the positive value because a length can’t be negative
a = 9
