Question

Please help! i don't know what to do, my formulas are not working for me. If anyone could please help i would really appreciate it. also if you do help me could you please list the formulas in the answer?

Complete the steps to find the surface area of the cylinder.

The radius is 3, the height is 4

The area of the base is _____ Pi in.2
The circumference of the base is ____ Pi in.
The area of the lateral surface is ✔ 24 Pi in.2
The surface area is _____ Pi in.2

Answer 1

Answer:The area of the base is

✔ 9

Pi in.2

The circumference of the base is

✔ 6

Pi in.

The area of the lateral surface is

✔ 24

Pi in.2

The surface area is

✔ 42

Pi in.2

Explanation:

Answer 2

• The radius is r = 3 in,
• The height is h = 4 in

The area of the base:

• A(b) = πr² = π(3²) = 9π in²

The circumference of the base:

• C = 2πr = 2π(3) = 6π in

The area of the lateral surface:

• A(l) = Ch = 6π(4) = 24π in²

The surface area:

• S = 2A(b) + A(l) = 2*9π + 24π = 42π in²
