The area of a circle is 225 what is the radius?
The radius is about 8.463 rounded to 3 decimal places
In a circle a 90 degrees sector has an area of 225 pie in squared What is the radius of the circle?
area = 225 pi = pi R squared/4 R = square root 900 = 30 in
What is the diameter of a circle with 225 pi cm?
The given measure, 225*pi cm is a linear measure so it cannot refer to the area. It could refer to the radius or the circumference of the circles, or the length of an arc or a segment of the circle. It could, of course refer to something else, but then the task of finding the diameter is near impossible. If it is the length of an arc or a segment, you require further information. Since that is not provided, perhaps one can assume that the measure does not refer to either. That leaves the radius or the circumference. If the radius is 225*pi then the diameter is simply 2*radius = 450*pi cm. If the circumference is 225*pi, then the diameter is circumference/pi = 225 cm.
What is the approximate area of a circle with radius of 15 in?
Area of a circle is (pi) x (radius)². So how do you want to approximate pi: We could choose 22/7, for example. So (15 in)² = 225 in², then multiply by 22/7 to get 4950/7 in², or 707 1/7 in².
How do you get the answer of -225-6?
-225 - 6 = -225 + (-6) = -231
The area of a circle is 225 what is the radius?
The radius is about 8.463 rounded to 3 decimal places
What is the area of a circle with a radius of 15 millimeters?
711
What is the equation to get the area of a circle if you have the radius?
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
What is the equation of a circle centered at the origin with a radius of 15?
x² + y² = 225.
What is the radius of a circle when the area is 225 pi?
pi*radius2 = 225*pi Divide both sides by pi and then square root both sides: radius = 15 units of measurement
In a circle a 90 degrees sector has an area of 225 pie in squared What is the radius of the circle?
area = 225 pi = pi R squared/4 R = square root 900 = 30 in
What is the radius of a circle if the area is 225?
The area is equal to pi times the radius squared, so dividing both sides by pi and taking the square root of both sides, we get that the radius is equal to the square root of 225/pi, or about 8.463.
What is the circumference of the circle with 225 cm its radius?
Circumference = 2*pi*r = 1413.7 cm = 14.137 metres
What is the radius of a circle when the area is 706.9?
The area of a circle is found by the equation pi times r2. To calculate the radius from the area we need to divide the area by pi and get the square root of the result. if we use 3.1418 as a close approximation of pi, we get 706.9 ÷ 3.1418 = 225 and the square root of 225 = 15.
What is the area of a circle of radius 15 cms?
It is pi x 15 x 15 = pi x 225 = 3.1415 x 225 = 706.84 square cms
If an arc length of 106 ft is traced by a rotation of 225 deg what is the radius of the circle?
Circumference = 106 x 360/225 = 169.6 ft = 2 x pi x radius so radius = 84.8/pi = 27 feet as near as makes no difference
A circle has a radius of 15 Find the diameter and the area?
diameter = 30 units area = 225*pi square units
