The area of a circle is calculated with the formula πr2, where r is the radius. Therefore, the area of a circle with radius 6cm would be π(6)2 = (36)π, or approximately 113.097 square centimeters.
64 pi ie just over 201 sq cm
3850m is the area of the a circle whose radius of 7meaters
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
The answer depends on what the "6cm" refers to.
C = ~37.7 cm A = ~113.1 cm2
The area of a circle is calculated with the formula πr2, where r is the radius. Therefore, the area of a circle with radius 6cm would be π(6)2 = (36)π, or approximately 113.097 square centimeters.
It depends on the relationship between the rectangle and the circles.
12 cm.
6/2 = a radius of 3 cm
6cm
The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
12 cm
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
Since the diameter is always twice the length of the radius, the length of the radius is 6cm.
