Formula of circle?
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
If Earth's radius was 3960 miles how long would the length of the Equator be?
The length of the equator would be approximately 24881.4 miles. Using the circumference formula 2(pi)(r) where pi is 3.141592654... and r is the radius (3960 in this case) you can find the length of the circle, the equator. 7920 in reality, is the diameter which is distance of a single straight line that starts and ends on the circle and passes through the center of the circle.
Formula for radius of circle?
radius = diameter/2
Formula for radius of a circle?
radius = diameter/2.
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
What is the circumference of a circle with the radius if 4?
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is formula for the area of a circle?
the formula for the area of a circle is 3.14 x radius squared
What is the formula for diameter radius circumference?
Radius is the distance from the outside of the circle to the center. Diameter is the distance ACROSS the circle, it's formula is: D = 2R (Diameter is 2 times the Radius) Circumference is the distance AROUND the circle. C = Pi D, where Pi is the constant 3.1415.... (look it up))
What is Pi R Squared?
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
