Question

Find the area of this semi-circle with diameter, d = 95cm. Give your answer rounded to 2 DP.

Answer 1

Answer:

Area of this semi-circle is 3,544.10 cm²

Step-by-step explanation:

Area of semi circle is$A= \frac{\pi r^{2} }{2}$

here d= 95 cm  , hence r= 95/2 =47.5 cm

Area is

$A= \frac{\pi r^{2} }{2}\\A= \frac{\pi \times 47.5^{2} }{2}\\A=3,544.10 cm^2$

Area of this semi-circle is 3,544.10 cm²
