Question

PLEASE HELP ASAP SOLVE WITH EXPLANATION 3

Answer 1

`65.1\text{cm}^2`

Explanation:

Area of Rectangle

`A=bh=(8\text{cm})(5\text{cm})=40\text{cm}^2`

Area of Semicircle

`\displaystyle A=(\pi r^2)/(2)=\frac{\pi (4\text{ cm})^2}{2}=8\pi\text{ cm}^2`

Combined Area

`A_(total)=A_(rectangle)+A_(semicircle)=40\text{cm}^2+8\pi\text{cm}^2\approx65.1\text{ cm}^2`
