Answer 1

[tex] \frac{180}{360} * \pi *20^2 + \frac{90}{360} * \pi * 7^2 *2 \\ \\= \frac{1}{2} * \frac{22}{7} *20*20 + \frac{1}{4} * \frac{22}{7} * 7 * 7 * 2 \\ \\=628.57+77 \\ \\=705.57[/tex]

Answer 2

Answer:

:area of semi circle +area of a circle

22/7(20)^2(1/2) + 22/7(7)^2

11(400)/7 + 22(7)

4400/7 + 154

628.57+154

782.57(approx)
