Question

Which is the best estimate of the area of the figure in square centimeters

Answer 1

B) 194.24cm²

Explanation:

Find the area of each section and add up the areas:

Area of Triangle

`A=bh`

`A=(1)/(2)(6)(8)`

`A=(1)/(2)(48)`

`A=24cm^2`

Area of Rectangle

`A=bh`

`A=(15)(8)`

`A=120cm^2`

Area of Semi-circle

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

`A=(1)/(2)(\pi*4^2)`

`A=(1)/(2)(16\pi)`

`A=8\pi cm^2`

Total area of figure

`A=24cm^2+120cm^2+16\pi cm^2\approx194.27cm^2`

Therefore, your best answer is 194.24cm²
