8cm. The radius is always half the diameter.

i don't know i think you should just try your best

The area of a circle with a diameter of two cm is about 3.1416 cm.

The area of a circle if the diameter was s 7ft is 38.48ft

Area of a circle = (1/4) x (pi) x (square of the diameter)

It depends on the ratio of what of the circle? Its circumference, diameter, area?

Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.

The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm

Area of a circle = pi*radius2

C = ~25.133 cm

The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2

radius=4cm diameter=8cm *radius is half the diameter

Area of any circle = pi*radius squared

Circumference of a circle: 2*p*radius or pi*diameter

the answer is 20.54

A = 5.093 cm2

8cm. The radius is always half the diameter.
