What is the radius of a circle that has an area of 706.5?
15 units (to 2 dp)
How do you get an area for a circle?
Area of a circle = Pi * radius2
If the radius of a circle is doubled what happens to the area of the circle?
the area of the circle is increased by 400%
What is the area of a circle with a diameter of 30m?
The formula for area of a circle is Pi x r (squared), A = Pi(rxr). So since the diameter is 30 you divide it by two and get 15 and then square it and multiply it by pi and get 706.86 meters.
Finding area of circle?
Area of a circle = pi*radius2
How do you find the area of a circle if you have the cicumfrence?
Divide the circumference by 2*pi which then will give you the radius and use pi*radius2 to find the area of the circle
What is the area of a circle whose cicumfrence is 8 pie?
If circ is 8pi the radius must be 4 so area is 16pi
What is the formula of the cicumfrence of a circle?
2*pi*radius or pi*diameter
What is the formula used to find cicumfrence?
It is area
How many acres in a circle with a cicumfrence of 1 mile?
Approx 2011 acres.
What is the area of a circle when the radius is 15?
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
Which best describes how to find the length of an arc in a circle?
Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
Area of circle 15 cm radius?
The area of a circle with a radius of 15 cm is: 706.9 cm2
What is the area of a full circle if the diameter is 30?
The area of the circle: pi*15*15 = 225*pi square measurements
What is the area of a circle with diameter equal to 15 ft?
The circle's area is 176.71 square feet.
What is the area of a circle if the diameter is 15?
The area is 176.714 units2
What is the equation to get the area of a circle if you have the radius?
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
