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.
Oh, dude, the radius of a circle is just half of the diameter, so for an 11-inch circle, the radius would be 5.5 inches. Like, it's just basic math, nothing to lose sleep over. So yeah, the radius is 5.5 inches, but who's really measuring, right?
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)
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)
Oh, dude, seriously? Okay, so the area of a circle is π times the radius squared. Since the diameter is 22 ft, the radius is half of that, which is 11 ft. So, the area would be π times 11 squared, which is like 121π square feet. Easy peasy, lemon squeezy.
