Question
Find the circumference and the area of a circle with radius 8cm.Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.8cmCircumference:Area:
Solution
To find the circumference and the area of a circle, we use the formulas:
Circumference = 2πr Area = πr²
Given that the radius (r) is 8cm and π is approximately 3.14, we can substitute these values into the formulas.
For the circumference: Circumference = 2 * 3.14 * 8 = 50.24 cm
For the area: Area = 3.14 * 8² = 3.14 * 64 = 200.96 cm²
So, the circumference of the circle is 50.24 cm and the area of the circle is 200.96 cm².
