Question

Work out the area of this quarter circle

Answer 1

`38.4895 cm^(2)`

Explanation:

πr^2

is the formula for area of circle and since quarter means 1/4, multiply the formula by 1/4 and you get
`(pi*r^(2) )/(4)` where pi is π and * is multiply so we get

(3.142 x 7^2)/4

3.142 x 49/4

3.142 x 12.25

=38.4895 cm^2
