Give me a problem on radius, diameter, circumference, and pi please
Problem:
A circular pizza has a diameter of 16 inches. What is the circumference of the pizza in terms of pi?
Solution:
The diameter of a circle is twice the radius. Therefore, the radius of the pizza is 16 inches divided by 2, which is 8 inches.
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference and r is the radius.
Plugging in the radius (8 inches) into the formula, we get:
C = 2π(8) = 16π inches.
Therefore, the circumference of the pizza, in terms of pi, is 16π inches.
