Question

Find the area and perimeter of a circle​

Answer 1

78.54
`cm^(2)` Area

31.42 cm Circumference/perimeter

Explanation:

A =
`\pi r^(2)`

C = 2
`\pi`r

A =
`\pi`
`5^(2)`

A = 25
`\pi`

A = 78.54

C = 2
`\pi`(5)

C = 10
`\pi`

C = 31.42

Answer 2

Explanation:

r=5 cm

area=πr²

perimeter=2πr

substitute the value of r and calculate.
