Question

Find the Circumference and Area of a circle with the information provided:
D-20ft
R=10ft

Answer 1

Circumference, C = 62.8 ft

Area, A = 314 ft²

Explanation:

where π = 3.14

Circumference, C = 2π(r)

= 2π(10ft)

= 20π ft

= 62.8 ft

Area, A = π(r²)

= π(10ft)²

= 100π ft²

= 314.1593654 ft²

= 314 ft²
