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 finding the centroid of a circle?
2[4(radius)/3(pi)]
If the diameter of a circle is 36 what is the radius?
The radius of a circle is always half of the diameter. Therefore, if the diameter of a circle is 36 units, the radius would be half of 36, which is 18 units. The formula for finding the radius from the diameter is radius = diameter / 2. So, in this case, the radius would be 18 units.
What is the area of a circle if the radius of a circle is 3.7cm?
The formula for finding the area of a circle is : pi(r) squared. So, that answer would be 13.69cm multiplied by pi, which is nearest to 3.14.
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
