The area is ~452.3 cm2
Area = pi*122 = 452.389 square cm to 3 dp
Using 3.14 as Pi the area of circle is: 113.03999999999999
Do you know how to find the area of a circle when you know the radius ? Good! Do that. Do you know how to find the area of a square when you know the length of the side ? Good! Do that. Now you have two numbers ... the area of the circle and the area of the square. The problem wants you to find the difference of these two numbers. Do you know how to use subtraction to find the difference of two numbers ? Good! Do that.
The area of a circle of radius 21 is 1386
The area is ~452.3 cm2
The circumference of circle with radius 12cm is 75.4cm
The area is 113.1 square cm.
Area = pi*122 = 452.389 square cm to 3 dp
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
Since there is no shaded part, the answer must be that its area is 0 square units.
Using 3.14 as Pi the area of circle is: 113.03999999999999
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
The diameter of circle A is 12cm so its radius must be 6cm.
