Circumference = 2*Ï€*radius = 20*Ï€ feet
20; the diameter of a circle is twice its radius.
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
10 cm
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
x2 + y2 = 400
Circumference = 2*Ï€*radius = 20*Ï€ feet
The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.
20; the diameter of a circle is twice its radius.
The radius of this circle is 10 units.
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
The radius is 3.183
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet
radius = diameter/2 circumference = 2*pi*radius or pi*diameter area = pi*radius2
