Area of the circle: pi*11^2 = 121*pi square units
the radius is half the diameter. radius is half of 11. Which is 5.5.
Diameter = 2 * radius = 11 cm
area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2
radisus: 11; diameter:22 (2X11)
2 X 11
Is the diameter of a circle was 11cm the radius would be 5.5cm as two radii equals a diameter.
Its usually defined by the diameter of the ball, like an 11 inch disco ball would have a diameter of 11 inches, not a radius of 11 inches.
Its radius is 11 feet and so its diameter is 2*11 = 22 feet
the radius is half the diameter. radius is half of 11. Which is 5.5.
Radius, r = diameter / 2 Then circumference = 2*pi*r and area = pi*r*r
Diameter = 2 * radius = 11 cm
area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2
radius = 11/2 = 5.5 cm
The radius is equal to 1/2 the diameter. 11 divided by 2 =5.5
radisus: 11; diameter:22 (2X11)
Diameter=2xradius. Therefore radius=diameter/2. In this case the answer is 5.5 feet
