Question

Find the circumference

Please help

Answer 1

147 is the circumference.

since the directions say to use 3 as pi, and we know that the radius is 7, we can say that

3 times 7^2 = A, which is 147

Answer 2

area = 147 cm²

circumference = 42 cm

Step-by-step explanation:

area of a circle =
`\pi` r²

• 
  `\pi` is 3
• r is 7 cm

area = 3 × 7²

= 49 × 3

= 147 cm²

circumference of a circle = 2
`\pi` r

circumference = 2 × 3 × 7

= 42 cm
