How many square miles in a 40 mile radius?
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
How do you find the radius of a circle if you don't have the area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
How do you find the area of a circle that has a diameter of 4. 2?
2*radius=diametre radius=2.1 Area=pi*(radius)^2 Area=3.1428*2.1*2.1 Area=13.86
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Find the area of a circle that has a radius of 8m?
Area = 201 m2
How many cubic ft in a cylinder 20 inches diameter and 16 inches high?
To start with. find the volume by determining the area, then multiply by height. A diameter of 20 inches gives a radius of 10. Area is radius times radius, time pi. So 10x10= 100. x 3.14 is 3140. Times 16 is 5024. But that is cubic INCHES- to get cubic feet, divide 5024 by 1728 (number of cubic inches in a cubic foot.
How many square miles in a 40 mile radius?
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
What is the area of a circle with a 16 foot diameter?
3.14 x R2 (diameter)2 3.14 x 16= 5024 5024 x 5024= 2524056
How to find filet area of an arc knowing arc length radius?
How to find the area of a fillet. Is it area =0.2146 radius squared
How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
Why do you find the area of a circle with pi times the radius squared?
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
How do you find the radius if you know the area of a circle?
Radius is the square root of (area divided by pi).
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
How do you find the area of a circle from a radius?
S = (pi) * (radius)2
How do you find the diametre if you have the area?
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
How do you find the radius of a circle if you don't have the area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
