3rd Question:

Answer 1st Option: (pi) x r^2

r = radius = 12/2 = 6 ft

Value of pi = 22/7

22/7 x ( 6 )^2 = 113 ft^2.........................Answer.

4th Quuestion:

Answer 1st Option: 1/2 ( pi) x (r)^2 + 5 x 8

So its a combination of a rectangle whose area is given by length x breadth and a semicircle whose area will be given by 1/2 ( pi) x (r)^2

And sum of both will result into the answer.

Radius = 8/2 = 4 ft

= 1/2 ( pi) x (r)^2 + 5 x 8

= 1/2 x 22/7 x (4)^2 + 40

= 25.14 + 40

= 65.14 ft^2...................Answer
