Question

The drawing is composed of a rectangle and a semicircle find the area of the figure to the nearest unit.

160 CM^2
260 CM^2
540 CM^2
580 CM^2

Answer 1

the complete question in the attached figure

we know that

[area of a figure]=[area of rectangle]+[area of semicircle]

area of rectangle=10*16------> 160 cm²

area of semicircle=pi*r²/2----> pi*8²/2-----> 100.48 cm²

so
[area of a figure]=[160]+[100.48]-----> 260.48 cm²--------> 260 cm²

the answer is
260 cm²
