How do you find the circumference and area of a circle with radius of 5 centimeters?

Answer 1

The circumference is #10\pi#, the area is #25\pi#.

You just need to apply the definitions: the circumference is #2\pi*r#, where #r# is the radius. In your case, #2pi*5=10\pi#.

On the other hand, the area is #pi*r^2#, in your case #pi*25#.

To find the circumference of a circle with a radius of 5 centimeters, you use the formula: ( C = 2\pi r ), where ( r ) is the radius. Substituting ( r = 5 ) centimeters into the formula, ( C = 2\pi \times 5 ). Therefore, the circumference is ( C = 10\pi ) centimeters.

To find the area of a circle with a radius of 5 centimeters, you use the formula: ( A = \pi r^2 ), where ( r ) is the radius. Substituting ( r = 5 ) centimeters into the formula, ( A = \pi \times 5^2 ). Therefore, the area is ( A = 25\pi ) square centimeters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
