Step-by-step explanation:
<u>Given dimensions:</u>
- r = 7 cm
- b = 2r = 14 cm
- h = r = 7 cm
<u>Find the area of semicircle:</u>
- A₁ = 1/2πr² = 1/2*3.14*7² = 76.93 cm²
<u>Find the area of triangle:</u>
- A₂ = 1/2bh = 1/2*14*7 = 49 cm²
<u>Find the shaded area:</u>
- A = A₁ - A₂ = 76.93 - 49 = 27.93 cm²
7n - 25/ 3
I hope that helps.
