Answer:
V = pi 36 units^3
V =113.04 units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
V = pi ( 2) ^2 *9
V = pi 36
Letting pi = 3.14
V =113.04
Answer:
1256.64
Step-by-step explanation:
To find the area of a circle, the formula is πr2.
R stands for radius, and since the radius of a circle is always half the diameter we can figure this problem out.
If the diameter is 40, the radius is 1/2 of that, so the radius is 20. Now knowing the radius is 20, plug that into our formula and then we'll get the answer.
A = πr2 = π · 20^2 ≈ 1256.63706
≈ 1256.64

Answer:
67.5 ft^2
Step-by-step explanation:
First find the area of the circle.
A = pi r^2
A = pi (8)^2
A = 64pi
There are 360 degrees in a circle
The shaded area has 121 degrees
The fraction is 121/360
The fraction shaded is 121/360
The fraction of the circle is the same as the area
121/360 A = 121/360 * 64 pi
area shaded = 67.54488889
To the nearest tenth
area shaded = 67.5
