A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
Area of ANY circle is (pi) x (radius)2 .
This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
Radius = 1/2 of the diameter = 12.5 cm.
A circle with a radius of 25 cm has an area of 1,963.5 square 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.
Area of a circle in square cm = pi*radius squared
4 cm radius = Area of 50.26548 sq. cm.
