Use 22/7 for pi. By the way, the number in the circle (the radius) is 5 cm.

The length of the diameter is 10 cm.

The circumference of the circle is 31.43 cm.

Radius, r = 5 cm

Diameter

= 2 r

= 2 × 5 cm

= 10 cm

Circumference

= 2 π r

= 2 × (22/7) × 5 cm

= 220/7 cm

Area

= π r²

= (22/7) × 5² cm²

= 550/7 cm²

You are given the radius. Lets call it r.

Whats the formula for the diameter, the circumference and area of a circle?

You should learn these by heart. If you don't know them, find them. Ever heard of Google?

Once you found those formula, write them here and we will then continue.

Hopefully no one will spoil you the answer thereby depriving you from your personal enhancement; that would be very inconsiderate of them.
