22 is the answer to this math problem
Answer:
It is the 3rd choice. It is 4 times as big as the smaller cylinder
Step-by-step explanation:
V = πr2h
r - radius
h - height
π - pi
= π(3)2(10)
enter into a calucaltor and you get 282.74
= π(6)2(10)
enter into a calucaltor and you get 1130.97
Divide 1130 by 282 and you get about 4

im not really sure but I wish my answer is right
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is

Where,
is the central angle in degrees.
Putting r=10 and
, we get



Therefore, the area of the sector is 12.5π sq. inches.
