What is the area of a circle with a radius of 25 cm?
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 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.
How many diameters is 10.5 cm?
a diameter is not a unit of measurement; it is the distance across a circle.
The area of a circle is the same as the area of a square whose side is 5 centimeters The radius of the circle is closest to?
The area of the square = 52 = 25 sq cm The formula for the area (A) of a circle is A = π r2 Therefore for the areas to be equal then π r2 = 25 : r2 = 25/π = 7.9577 (4dp) Then r = √7.9577 = 2.82 cm The nearest integer measurement of the radius is 3 cm.
What is the area of a circle ewith a diameter of 10cm?
Using 3.14 as Pi the area of circle is: 78.5
What is the area of a circle with a radius of 25 cm?
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
What radius area of circle is 25 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
What is the area of a circle with a diameter of 25 cm?

What is the circumference of a circle that has an area of 25 centimeters squared?
The circumference of a circle that has an area of 25 centimeters squared is about 17.72 cm
What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 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.

What is the area of a 3 cm circle?
The area of a 3 cm circle is: 7.069 square cm
The area of a circle is the same as the area of a square whose side is 5 centimeters The radius of the circle is closest to?
The area of the square = 52 = 25 sq cm The formula for the area (A) of a circle is A = π r2 Therefore for the areas to be equal then π r2 = 25 : r2 = 25/π = 7.9577 (4dp) Then r = √7.9577 = 2.82 cm The nearest integer measurement of the radius is 3 cm.
What is the area of a circle ewith a diameter of 10cm?
Using 3.14 as Pi the area of circle is: 78.5
What is the radius of a circle with the area 25 pi cm squared?
Area = (pi) R225 pi = pi R2R2 = 25R = 5 cm
What is the radius of a circle if 10 cm is the diameter?
5cm since radius is one half the diameters.
How many area are there in a 100 cm perimeter shape?
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.
