Best Answer

The formula for the circumference of a circle is 2(pi)(r). From your example, r=4 cm

So the answer would be 2(pi)(4 cm), or 8pi cm (this is a little more than 24 cm, since pi=3.14).

What is the radius of a circle if its a diameter 4 cm?

Its radius is: 4/2 = 2 cm

What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm?

Area circle = π × radius² Area smaller circle = π × (4 cm)² = 16π cm² Area larger circle = π × (10cm)² = 100π cm² → probability inside smaller circle = area_smaller_circle/area_larger_circle = 16π cm²/100π cm² = 16/100 = (4×4)/(4×25) = 4/25.
