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

Anastasy [175]

Answer:

The area of the semi-circle

A = 1320.37 cm²

Step-by-step explanation:

<u><em>Explanation:-</em></u>

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

The radius of the circle 'd' = 2r

$r = \frac{d}{2} = \frac{58}{2} = 29$

The area of the semi-circle

$A = \frac{1}{2} \pi r^{2}$

$A = \frac{1}{2} (3.14) ((29))^{2}$

A = 1320.37 cm²
