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 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 using pi if radius is16cm?
A circle with a radius of 16 cm has an area of 804.25 square cm.
What is the center and radius of the circle of x squared plus y squared -4x -6y -3 equals 0 enscribed on the Cartesiian plane?
x2+y2-4x-6y-3 = 0 Using the appropriate formula it works out as:- Centre of circle: (2, 3) Radius of circle: 4.
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 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 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.
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 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 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.
How do you find circumference using radius'?
Circumference of a circle = 2*pi*radius
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
What is the area of a circle using pi if radius is16cm?
A circle with a radius of 16 cm has an area of 804.25 square cm.
What is the area of a circle with a radius of 21cm?
The area of a circle is 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. Plugging in the radius of 21cm into the formula, we get A = 3.14159 x (21)^2 = 1385.44 square centimeters. Therefore, the area of a circle with a radius of 21cm is 1385.44 square centimeters.
