Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)

The number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5
<h3>How to determine the number</h3>
From the information given;
The bricklayer needs = 100 pieces of angle
The number of cuts = 54
Length of cuts = 3/ 16'' Inches
a. To determine the number of cuts form a 20% length, we have to multiply the length by the percentage and by the initial number of cuts
= 20/ 100 × 3/ 16 × 54
= 0. 2 × 0. 1875 × 54
= 2. 0
The number of cuts would be 2
b. To determine the number of pieces of 20' angle to have 100 pieces we would divide the initial number of pieces by the angle
= 100/ 20
= 5 pieces
The number of pieces of 20' angle is 5
Thus, the number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5
