Question

Find the area of this semi-circle with diameter, d = 58cm.
Give your answer rounded to 2 DP.

Answer 1

The area of the semi-circle

A = 1320.37 cm²

Explanation:

Explanation:-

Given the diameter of the circle 'd' = 58cm

The radius of the circle 'd' = 2r

`r = (d)/(2) = (58)/(2) = 29`

The area of the semi-circle

`A = (1)/(2) \pi r^(2)`

`A = (1)/(2) (3.14) ((29))^(2)`

A = 1320.37 cm²
