Diameter = 2*Radius. You should now be able to deal with this and similar questions.
Radius = 1/2 of the diameter = 12.5 cm.
50 cm is the diameter.
a circle of diameter 25 what is its radius
This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
If the diameter is 25 then the radius must be 12.5
Radius of circle: 25/2 = 12.5 feet
Radius = 1/2 (diameter) = 25 inches.
Radius = 1/2 of the diameter = 12.5 cm.
50 cm is the diameter.
12.5 inches
If a circle is 50 feet wide, that means its diameter is 50 feet. The radius of a circle is half the diameter, therefore the answer is 25 feet.
a circle of diameter 25 what is its radius
The answer is 50 inches.
A circle with a radius of 12.5 feet (25/2) has an area of 490.87 square feet.
Are you referring to the circle's diameter or its cicumference? If you mean diameter then the radius is 50/2 = 25 feet If you mean circumference then the radius is 50/(2*pi) = 7.957747155 or about 8 feet
No, area of a circle is pi x radius x radius Radius is half the diameter. So the diameter of something giving 11.5 square feet as an area, must be much much smaller.
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
