What is the radius of a circle with an area of 78.5 cubic inches? use 3.14 for pi. enter your answer in the box.

5 inches

Step-by-step explanation:

1. You must use the formula for calculate the area of a circle, which is shown below:

Where is the radius of the circle.

2. You know the area of the circle, therefore, you can solve for the radius, as following:

3. Now, you must substitute the value of the area into the equation above. Then, you obtain the following result:

what golf ball

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
