Answer:
105.12
Step-by-step explanation:
area of rectangle = 10 x 8 = 80
area of semi circle = 3.14 x 4^2 (4 because the diameter is 8 so half of it)
= 50.24
50.24 / 2 = 25.12 (as it is a semi-circle)
80 + 25.12 = 105.12
Answer:
130.24
Step-by-step explanation:
8*10+3.14*4^2=
80+50.24=130.24 ft^2
Cut the shape into a semi-circle and rectangle (with length 10 and width 8).
You'll find the radius of the semi-circle is 4.
The area of the rectangle is 80.
Then use the pir^2 formula but replace pi with 3.14
3.14 multiplied by radius 4 squared is 50.24
50.24 plus 80 is 130.24 ft squared.
