What is the radius for 100?
The radius of a circle is 1/2 of its diameter
What is the formula for the area of a circle with a diameter of 100?
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius of the circle. To find the radius from the diameter, you divide the diameter by 2. So, for a circle with a diameter of 100, the radius would be 50. Plugging this into the formula, the area would be A = π(50)^2 = 2500π square units.
What is the area of a circle with 100 mm diameter?
A circle with a radius of 50 mm has an area of 7853.98 square mm

How many square miles in a 100 mile radius?
This is the area of a circle with a radius of 100 miles →area = π × radius² = π × (100 miles)² = 10,000π sq miles ≈ 31416 sq miles

A radio station's signal has a radius of 100 miles. If you drive at a constant speed of 40 miles an hour nonstop directly across the diameter of the signal how long can you listen to the station be?
5 hours The radius is 100 miles, so the diameter of the circular listening area is 200 miles. If you start at one side of the circle and drive straight through to the other side you are driving 200 miles. Divide the 200 miles by 40mph and you get 5 hours.
How do you find the perimeter if the radius is 100 millimeters?
First of all, you have to promise us that you're talking about a circle.We're going to assume that, since you mentioned 'radius'.The perimeter of a circle ... usually called its 'circumference' ... is (pi) x (the circle's diameter).The circle's diameter is (2) x (its radius).Diameter = 200 millimetersCircumference = (pi) x (200) = 628.319 millimeters (rounded)
