Question

Use pi to answer this

Answer 1

218.5

Explanation:

Half circle area formula: π x
`r^(2)` all divided by 2.

The diameter is 10, but since radius is half of the diameter, it will be 5.

π x
`5^(2)` =25π

3.14 x 25=78.5

Now for the rectangle:

14 x 10=140

Now add the half circle and rectangle together:

140+78.5=218.5

Final answer

218.5

Answer 2

319.25

Explanation:

area of square: 14*14=196

area of half circle: a=π(5)^2 =246.49 area of half=123.245
