What is the area of a circle radius equal to 2?
Using 3.14 as Pi the area of circle is: 12.56
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
What is the circumference of a circle if the radius is 49?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 49, the circumference would be ( C = 2\pi \times 49 ), which equals approximately 307.76 when using ( \pi \approx 3.14 ). Thus, the circumference of the circle is about 307.76 units.
What is the circumference of a 11 cm radius?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with an 11 cm radius, the circumference is ( C = 2\pi(11) ), which equals approximately 69.44 cm when using ( \pi \approx 3.14 ).
What is the area of circle by using 3.14?
Area = (3.14) x (radius) x (radius) "Radius" means the distance from the center of the circle out to the circle's curved line.
What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
What is the area of a circle radius equal to 2?

How do you divide a circle into 8 equal parts using 3 lines?
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
What is the circumference of a circle if the radius is 49?

What is the area of circle by using 3.14?
Area = (3.14) x (radius) x (radius) "Radius" means the distance from the center of the circle out to the circle's curved line.
What is the area of a circle with the radius of 100?
The area of a circle can be calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 100, the area of the circle would be A = π(100)^2 = 10000π square units. This simplifies to approximately 31415.9 square units.
What is the circumstance if the radius is 21?
The circumstance of a circle is typically referred to as its circumference, which can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 21, the circumference would be ( C = 2\pi \times 21 ), which equals approximately 131.95 when using ( \pi \approx 3.14 ). Thus, the circumference of a circle with a radius of 21 is about 131.95 units.
What is the circumference of a circle whose radius is 20?
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 20, the circumference would be C = 2 * 3.14159 * 20 = 125.6636 units.
What is the area of a circle which has a radius equal to 17?
Using 3.14 as Pi the area of circle is: 907.46
