Find the area of the circle a. 48.25 sq. in.
b. 62.8 sq. in.
c. 88.23 sq. in.
d. 78.5 sq. in.

Area of a given circle the for is πr² where r is the radius but from the question we only have diameter. to get our radius we divide diameter by 2. which is 10/2=5

Π×5²=78.54m²

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree
