Question

Find the area and circumference of the circle below round your answers to the nearest hundred

Answer 1

Area: 28.27
circumference: 18.85

Answer 2

The formula to find area of circle is given by:

$A = \pi r^{2}$

where r is radius of circle and pi =3.14

From the figure we have diameter = 6 meters

radius = half of diameter = 3 meter

plugging this value in the formula:

$A = (3.14) (3)^{2}$

Area= 28.28 square meter.

Formula to find circumference is :

$C = 2\pi r$

$C = 2(3.14)(3)$

C =18.84 meter

Answer: circumference is 18.84 m
