Area of a circle = pi*radius2
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
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 the circle in square cm = pi*radius2
314.29 cm
The area of a circle whose diameter is 10 cm is: 78.54 cm2
Area of a circle = pi*radius2
A circle with a radius of 10 cm has an area of 314.16 square cm

Area of a circle = pi*radius2
Area = 78.54 cm2Circumference = 31.42 cm
The area of a circle with a radius of 10 cm would be 100 times pi, or, rounded to the nearest hundreth, 314.15 cm2.
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.
