Question

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

Answer 1

Answer:

The area of the semi-circle

                                  A = 1320.37 cm²

Step-by-step explanation:

Explanation:-

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
