What is the radius of a circle which has equal numeric values for the circumference and the area?
r = 2
What is the radius of a circle if its circumference and area both equal 246?
A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
What does circumference mean math term?
Circumference refers to the size of something as given by the distance around it, e.g. the circumference of a circle is the distance around it, or its perimeter. The circumference of a circle can be used in the following formula to determine other values in a circle: C=2πr, or C=πd, where C is the circumference of the circle, r is the radius of the circle, d is the diameter of the circle and equivalent to twice the radius, and pi is, well, pi.
What are the parts of a circle?
A part of a circle is called an arc. The defined values for a circle are: radius, diameter, chord, area, circumference, and the arcs. There is the circumfrence, semi circle, arc, diameter,chord,segment,radius,quaderent
What is the circumference of a circle if the radius is 48?
Just use 2 x (pi) x radius (pi) values is 22/7 or 3.142
How do you fimd the radius and diameter of a circle?
If you know the circumference, use the formula for circumference (C=pi*diameter), but rearrange it to get Diameter= circumference/pi. Then just sub in values.
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
Can the radius of a circle be a decimal number?
Yes, the radius of a circle can be a decimal number. The radius is the distance from the center of the circle to any point on its circumference, and this distance can be measured in decimal form. In fact, many real-world measurements result in decimal values for the radius of a circle.
How do you do cercomference?
The circumference of a circle can be calculated using the formula C = 2 * π * r, where r is the radius of the circle. Or you can use C = π * d, where d is the diameter of the circle. Just plug in the values of r or d to find the circumference.
Why are the area and the circumference of a circle the same?
Frankly, I haven't the slightest clue as to what you mean by "the same." The circumference of a circle is defined as pi x 2 x radius, or pi x diameter. The area is pi x radius squared. Therefore, for real circles, these values can only be the same if the diameter measure is the same as the radius squared. This works is the radius is 1 or 2.
What is the radius of a circle of 480 feet?
Depending on what "a circle of 480 feet" means, the radius will have different values. If the radius is 480 feet, then that is your answer. If the diameter is 480 feet, then its radius is 480/2 = 240 feet. If the circumference is 480 feet, then its radius is 480/2(pi) = 240/(pi) = 76.39 feet.
Is the circumference always numerically bigger than the area?
No, the circumference is not always numerically bigger than the area. For example, in the case of a circle with a radius less than 1, the area (πr²) can be greater than the circumference (2πr). As the radius increases, there will be values where the area surpasses the circumference, but the relationship varies based on the shape and dimensions being considered.
