Question

Shaded area is about

Answer 1

41/Diameter =sin37
Diameter= 41/sin37
41x5/3 = 205/3 hence radius is 205/6

Answer 2

so the 205 is divide by 6

Answer 3

yeah..thts radius..so ur area is 0.5(pi)r^2

Answer 4

same with 41/sin37

Answer 5

what with that?

Answer 6

like divide

Answer 7

yeah

Answer 8

diameter is 68.12

Answer 9

so radius is 34.06

Answer 10

yea then i solve it by 2pi34.06sq right

Answer 11

half x pi x 34.06sq

Answer 12

Area of circle is 2pi34.06, but you don't want a circle, you want half a circle. Area of half a circle is (1/2)2pi34.06.
