The curved part of this figure is a semicircle. what is the best approximation for the area of this figure? 18+12.125π units² 36+24.25π units² 36+12.125π units² 18+24.25π units²

18+12.125π units²

Step-by-step explanation:

The diameter of the semicircle can be found by the use Pythagoras theorem.

Δx²+Δy²=d²

Δx=3--1=4

Δy=3--6=9

d²=4²+9²

d=√(16+81)

Area=πr²/2

=π×(√(16+81)/2)²÷2

=[π×(97)/4]/2

=97π/8

=18+12.125π units²

97π/8 is equivalent to 18+12.125π units²

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

it could be 1,3 and more others to create a cylinder.
