Question

Find the find the area and the circumference of the circle round your answer to the nearest hundredth ​

Answer 1

Area = pi * r^2
Area = pi * 12^2 = 452.39 square units
Circumference = 2(pi) * r
2 * pi * 12 = 75.40 units

Answer 2

area = 452.39 square units

circumference = 75.40 square units

Explanation:

area =
`\pi r^(2)`

r = 12

452.389

circumference =
`\pi *d`

d = 2r

r = 12

d = 24

75.398
