Answer:
432 cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
If the radius is multiplied by 9 then the circumference will also be increased by a factor of 9
given C = 48 cm
then circumference of new circle = 9 × 48 cm = 432 cm

Find the surface area of a triangular prism that has a height of 11 meters and the triangular base shown. All dimensions are in meters.
S
A
=
m
2
Answer:
146 m²
Step-by-step explanation:
The total base area = base x length = 4 x 11 = 44 (1)
The area of each triangular surface = /2 x base x height = 1/2 * 4 * 3.5 = 7 and the areas of both triangular surfaces = 2 x 7 = 14 (2)
The surface area of each of the lateral surfaces = side of triangle x length = 4 x 11 = 44
The area of both lateral surfaces = 2 x 44 = 88 (3)
Adding up (1), (2) and (3) gives us 146 m² as the total surface area

To predict volcanic eruptions scientists may use a seismograph to detect small earthquakes out of the 169 active volcanoes in the U.S. about 130 are in Alaska. About how many active U.S. volcanoes are not is Alaska?
Answer:
39 active volcanoes.
Step-by-step explanation:
Subtract 169 (whole) from 130 (part). 9 - 0 = 9, 6 - 3 = 3, and 1 - 1 = 0. Therefore, 169 - 130 = 39
When the expression x²-4x-32 is factored to (x-8)(x+h), where h is a constant, what is the value of h? (will give 50 points+brainliest)
Answer:
h = 4
Step-by-step explanation:
Answer:
H = 4 given -an expression x² - 4x - 32
To find -Value of h
Solution -[tex] {x}^{2} - 4x - 32[/tex]
Solving by splitting middle term
[tex] {x}^{2} - 8x + 4x + 32[/tex]
[tex] x(x - 8) + 4(x - 8)[/tex]
[tex](x - 8)(x + 4)[/tex]
equating this with (x-8)(x + h)
Value of H = 4

A coin is tossed 3 times and a sequence of heads and tails is recorded.
a) Determine the number of points in the sample space
b) Construct a tree diagram and list the sample space
Find the probability that:
c) No heads are tossed
d) Exactly one head is tossed
e) Three heads are tossed
Solution:
Total number of trials = 250.
Number of times three heads appeared = 70.
Number of times two heads appeared = 55.
Number of times one head appeared = 75.
Number of times no head appeared = 50.
In a random toss of 3 coins, let E1, E2, E3 and E4 be the events of getting three heads, two heads, one head and 0 head respectively. Then,
(i) getting three heads
P(getting three heads) = P(E1)
Number of times three heads appeared
= Total number of trials
= 70/250
= 0.28
(ii) getting two heads
P(getting two heads) = P(E2)
Number of times two heads appeared
= Total number of trials
= 55/250
= 0.22
(iii) getting one head
P(getting one head) = P(E3)
Number of times one head appeared
= Total number of trials
= 75/250
= 0.30
(iv) getting no head
P(getting no head) = P(E4)
Number of times on head appeared
= Total number of trials
= 50/250
= 0.20
