12.4pi

Step-by-step explanation:

Step-by-step explanation:

area of square = L x L

=10 x 10 = 100

area of circle = π x r x r

to get r, divide the square into two triangles

then use Pythagoras theorem to get the hypothenuse

(10x10)+(10x10)=hxh

200=h²

√200=h

h=14.14

h=diameter

therefore, the radius=7.07

now back to the area of a circle

π x7.07²

=49.98π

area of shaded part=area of circle - area of square

=49.98π- 100

based on context clues you gave i'm assuming the answer would be c.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
