Question

Find the Area of the figure below, composed of a square and four semicircles. Rounded to the nearest tenths place

12

Answer 1

370.1
`units^(2)`

Explanation:

Square

a =
`s^(2)`

a =
`12^(2)` = 144

Semi - Circle:

a = 1/2(
`\pi r^(2)`)

a = 1/2(3.14)(36) The radius is 1/2 the diameter of 12 (6)
`6^(2)` = 36

a = 1/2(113.04)

a = 56.52

144 + 4(56.52)

144 + 226.08

370.08 rounded to the nearest tenths place 370.1
