Question

What is the area of a semicircle with a diameter of 8 feet? Estimate using 3.14 for TT
A) 25.12 ft ²
B) 50.24 ft²
C)200.96 ft ²
D) 100.48 Ft²​

Answer 1

Answer: 25.12 ft²

Step-by-step explanation:

So  r = D ÷ 2

Since the area of a circle = πr²

then the area of a semi-circle =  (¹/₂π (¹/₂D)²)

Area of a semicircle given the diameter = (¹/₂π (¹/₂D)²)

                                                                  =  (¹/₂(3.14) (¹/₂ 8ft)²)

                                                                  = 25.12 ft²
