Answer:

The circumference of the circle is 62.8 mm.

Step-by-step explanation:

We must first know the formula for finding the circumference.

C = dπ

Let's plug in our diameter. We will use 3.14 for pi.

C = (20)(3.14)

Multiply the numbers together.

C = 62.8

So, the circumference of a circle with a diameter of 20 mm is 62.8 mm.

Answer:

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
