Answer:
area= 62.88
Step-by-step explanation:
to find the area of the whole figure take the diameter of the circle witch is 8 and multiply it by 11. the area of the whole figure including the semi-circle is 88.
now find the area of the whole circle and divide it in half.
A= pi * r^2 / 2
A= 3.14 * 4^2 /2
A= 3.14 * 16 / 2
A= 25.12
Now take the area of the semi-circle and subtract it from the whole figure.
88-25.12=62.88

2) B. 25 cm ^2The area of a regular pentagon can be found using the formula.
s=side length
A≈960 square feet
The apothem of a square is half of the side length. 2.5*2=5. 5^2 = 25cm^2
