10 cm Cutting out a quarter of the circle doesn't affect the radius, which is half of the diameter.
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.
You double the radius.. if the radius is 10 the diameter is 20.
20; the diameter of a circle is twice its radius.
The radius of this circle is 10 units.
The radius is 3.183
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
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)
The radius of a circle is the distance from the center of the circle to any point on its circumference. In this case, if the circle has a diameter of 20 feet, the radius would be half of that, which is 10 feet. So, the radius of a 20 ft circle is 10 feet.
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
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.
The radius of a circle whose circumference is 40pi is 20 units.
20 mm. The diameter is always twice the radius.
