For a circle with a diameter of 100 cm, the area is ≈ 9,503.32 cm2
Area = pi*502 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.
Approximately 100, give or take
The area will depend upon the shape itself - a perimeter of 100 cm could be a square 25 cm by 25 cm (area 25 cm × 25 cm = 625 cm²) or a rectangle 30 cm by 20 cm (area 30 cm × 20 cm = 600 cm²) or any other shape. The maximum area is a circle with a circumference of 100 cm which has an area of approx 795.77 cm² Which means any shape with a perimeter of 100 cm has an area which is less than or equal to approx 795.77 sq cm.
For a circle with a diameter of 100 cm, the area is ≈ 9,503.32 cm2
Area = pi*502 square cm
Using 3.14 as Pi the area of circle is: 314.0
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.
The area of a 3 cm circle is: 7.069 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.
The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.
Area = pi*r2 = 100 so r2 = 100/pi and therefore, r = sqrt(100/pi) = 10/√pi = 5.64 cm
