The area is 113.1 square cm.
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
It is: (pi*radius squared)/4
Since there is no shaded part, the answer must be that its area is 0 square units.
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area is ~452.3 cm2
The area is pi*radius2 = 452 cm2, approx.
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
Since there is no shaded part, the answer must be that its area is 0 square units.
It is: (pi*radius squared)/4
You find the area of the entire circle (pi x radius^2), and then multiply it by 1/4 or 0.25.
Using 3.14 as Pi the area of circle is: 113.03999999999999
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
It is reduced by a quarter. If you halve the you also halve the diameter The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.
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.
