Answer:
Step-by-step explanation:
To solve this problem we first need to find the diameter of the circle. We are told the point is the circle, so we can assume it is the center of the circle. To find the diameter we can use the Pythagorean Theorem:
The diameter is units, which means the radius is . From here we can calculate the area of the circle:
Now we need to subtract the area of the triangle from the area of the circle. Calculate the area of the triangle:
Subtract the triangle area from the circle area to get the area of the shaded area:
Answer:
So find the what?

Answer:
x=3 15/16 hours together
Step-by-step explanation:
the painter paints 1/7 of the house in 1 hour
the assistant paints 1/9 of the house in 1 hour
x=# of hours it takes them together to paint the house
(1/7)x+(1/9)x=1 (job finished)
multiply both sides by the LCM which is 63
63(1/7)x+63(1/9)x=63(1)
9x+7x=63
16x=63
x=63/16
x=3 15/16 hours together
(A)
