Question

The figure consists of a quarter circle and a parallelogram. what is the area of the composite figure? use 3.14 for . Round to the nearest whole number.

70in.²
84in.²
154in.²
224in.² ​

Answer 1

224

Explanation:

the area of a circle is
`\pi`
`r^(2)`, so for the circle plug in your numbers:

(3.14)(
`14^(2)`) = 615.44

divide this by 4 because t=in the picture you only have a fourth of a circle:

615.44 / 4 = 153.86

the formula for area of a trapezoid is
`(a + b)/(2)` × h

so plug in your values:
`(14+14)/(2)` × 5

you get 70

add 70 and 153.22

70 + 153.22 = 223.22

this can round to 224
