Question

Work out the area of a semicircle with radius 3 cm. Give your answer in terms of t. 3 cm

Answer 1

Answer:

Area = 4.5 π cm²

Step-by-step explanation:

Area of semicircle = $\frac{\pi r^2}{2}$

Where r = 3cm

=> Area = $\frac{\pi(3)^2 }{2}$

=> Area = $\frac{9\pi }{2}$

=> Area = 4.5 π cm²
