Its radius is: 4/2 = 2 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.
A circle with a radius of 4 cm has an area of 50.27 square cm.
2 cm
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
4 cm radius = Area of 50.26548 sq. cm.
Its radius is: 4/2 = 2 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.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
2 cm
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
Radius = 1/2 of diameter = 4 cm
A circle that is 25.13272 cm in circumference.
This indicates a radius of 4 cm, in which case the area of the circle is: 50.27 square cm
