Answer:
<h2>
4200πcm²</h2>
Step-by-step explanation:
Given the formula for the surface area of a cylinder as S = 2πr(r+h) where r is the radius of the cylinder's base and h is its height.
Given parameters
base radius of the cylindrical pole = 10 cm
Height of the cylindrical pole = 2 m
Since 100 cm = 1 m, then 2 m = 200 cm
Height of the cylindrical pole (in cm) = 200 cm
Required
Surface area of the pole (in cm²)
Using the formula for finding the surface area of a cylinder as shown above;

Hence the surface area of the pole in square centimetres is 4200πcm²

Work:
12x12= 144
9x9= 81
144+81=225
225 square rooted is 15
A is the answer to the question
I’m going to have to say answer D but I could be wrong
Answer:
A.) V = 160π
B.) V = 502.4 inches^3
Step-by-step explanation:
Part A:
<u>Formula for the volume of a cylinder: V = π * r^2 * h</u>
r^2 can be broken into r * r
π can be represent by 3.14
It is the same as: <u>V = r * r * h * 3.14</u>
V = 4 * 4 * 10 * π
V = 160π
Answer: V = 160π
Part B:
<u>Step 1: Plug in</u>
V = 4 * 4 * 10 * 3.14
V = 16 * 31.4
V = 502.4 inches^3
Answer: V = 502.4 inches^3
