Determine the radius and diameter of the Circle, considering pi equal to 3.14 if its area is 78.5

Determine the radius and diameter of the Circle, considering pi equal to 3.14 if its area is 78.5 cm3 draw this Circle and Draw its radius and diameter.

To solve this problem, you need to find the radius of the ball. Consider the condition of the assignment and analyze it.

By the terms of the assignment, we know that the volume of the ball is seventy-eight and a half cubic centimeters.

For the further solution, we write down the formula for the volume of the ball;

V = 4/3 * п * r^3, where V is the volume of the ball, P is the “PI” number equal to 3.14, r is the radius of the ball;

From the formula for the volume of the sphere, we find the radius and write down the resulting expression;

r3 = V / 4/3 / п;

Substitute the values;

r3 = 78.5 / 3.14 * 3/4;

r3 = 18.75;

Take the cube root of the left and right sides;

r = 4.33cm, ball radius.
