Answer:
74 + 4 π ft^2
Explanation:
Just a bit of a piecemeal.
2 rectangles and a half circle. We have all the dimensions.
1. Let's solve the big one first A = lw, putting in the numbers A = 4*15 = 60
2. The smaller one A = lw, putting int eh numbers A = 2 * 7 = 14
3. Now, the semi-circle. We know the diameter by deducting 12 from the total length, which is 9 + 7 = 16 in = 4 ft
The radius of the circle is half of the diameter, so the radius is 2 ft
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
Substituting the values, we get:
A = π(2)^2
A = 4π
The area of the circle is 4π square ft^2
Add: 60 + 14 + 4π = 74 + 4 π ft^2
