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
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
A circle with a radius of 2 cm has an area of 12.57 square cm.
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
If you mean area of a circle with a radius of 25 cm then it is:- Area = pi*252 = 1963.495 square cm to 3 decimal places
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
