What is the radius of a circle that has an area of 78 cm2?
Divide the area by the value of Pi to get the diameter. Divide the diameter by 2 to get the radius !
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find radius when area is given?
Divide the area by pi and then square root it this will give the radius of the circle.
How do you find the radius of a circle using an equation?
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
What is the diameter of a circle when the area of the circle is 254.34?
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
What is the radius of a circle that has an area of 78 cm2?
Divide the area by the value of Pi to get the diameter. Divide the diameter by 2 to get the radius !
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find radius when area is given?
Divide the area by pi and then square root it this will give the radius of the circle.
How do you solve Circle Area conjecture?
divide the radius by Pi2
How do you find the radius of a circle using an equation?
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
How do you find the circumfrence of a circle when you have the area?
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
What is the diameter of a circle when the area of the circle is 254.34?
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
How do you calculate the area of a circle when you have the circumference?
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
What is the area of a circle that has a diameter of 34 ft?
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.
What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.
