Answer:

[tex]c = 62.83 ft[/tex]

[tex]a = 314.159 {ft}^{2} [/tex]

Step-by-step explanation:

[tex]c = 2\pi \: r \\ c = 2 \times \pi \times 10 \\ c = 62.83ft[/tex]

[tex]area \\ = \pi {r}^{2} \\ = \pi \times 10 \times 10 \\ = 314.159 {ft}^{2} [/tex]

hope this helps

Answer:

C = 62.83 ft.

A = 314.2 ft²

Step-by-step explanation:

circumference of a circle = 2πr

where r = dia./2 = 20/2 = 10 ft.

C = 2 π * 10

C = 62.83 ft.

area of a circle = 2 r²

where r = 10 ft

A = π * 10²

A = 314.2 ft²
