Question

Find the area of the shaded region to the nearest tenth

Answer 1

your answer is 14 (rounded to the nearest tenth) cause the r of the circle is 4 and to find area is pi*r^2 and that is 50.24 minus the 64 and that is 13.76

Answer 2

13.73 square units

Explanation:

Area of shaded region = Area of a square - area of a circle

Area of a square = side^2

side = 8

Area of a square =
`8^2= 64`

Area of a circle =
`\pi r^2`

Radius of a circle = diameter divide by 2 =
`(8)/(2) =4`

Area of a circle =
`\pi (4)^2=16\pi`

Area of shaded region = Area of a square - area of a circle

Area of shaded region =
`64-16\pi =13.73` square units
