Question

Find the circumference and the area of a circle with diameter 6 yd.

Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

Hey there!

Radius ⇒ d/2 = 6/2 = 3

Radius = 3 yd

Circumference = 2πr

⇒ 2 × 3.14 × 3

⇒18.84 yd

Area = πr²

⇒3.14 × 3²

⇒3.14 × 3 × 3

⇒28.26 yd²

Answer 2

`c = \pi \: d = 6 * 3.14 = 18.84 \: yd`

`radius = (diameter)/(2) = (6)/(2) = 3`

`area = \pi \: r {}^(2) = 3.14 * 3 {}^(2) = 3.14 * 9 = 28.26 \: yd {}^(2)`
