Question

Find the circumference and area of a circle with radius 8cm. Use the value 3.14. Do not round your answers. Be sure to include the correct units in your answer.

Answer 1

The circumference is 50.24 cm and the area is 200.96 cm²

Step-by-step explanation:

The circumference of a circle is equal to

C = 2πr

Where π = 3.14 and r is the radius. Replacing r = 8 cm, we get:

C = 2(3.14)(8 cm)

C = 50.24 cm

On the other hand, the area of a circle is calculated as

A = πr²

Replacing r = 8 cm, we get:

A = (3.14)(8 cm)²

A = (3.14)(64 cm²)

A = 200.96 cm²

Therefore, the circumference is 50.24 cm and the area is 200.96 cm²
