Question

Find the circumference and area of a circle with radius 3 yd. use the value 3.14 for pie

Answer 1

Answer: circumference = 2Πr²

Where r= 3

Π=3.14

Therefore Circumference = 2×3.14× 3²

= 2×28.26

Circumference=56.52

Formula:

Subtitute in 3 for r.

Solve and the answer is 28.26

Answer 2

Answer:

Circumference: 18.84 yards

Formula: 2$\pi$r

Plug in 3 for r.

Solve and the answer is 18.84

Area: 28.26 yards squared

Formula: $\pi r^{2}$

Plug in 3 for r.

Solve and the answer is 28.26
