If the radius of the circle is 8 cm what is the circumference of the circle?
If the radius of the circle is 8 cm the circumference is: about 50.27 cm (r x 2 x pi = circumference).
What is the approximate area of a circle with 16 cm diameteer?
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
What is the diameter of a circle if the radius is 8 Cm?
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
What is the radius of a circle that has a diameter of 8 Cm?
Radius = 1/2 of diameter = 4 cm
What is the radius of a circle with a diameter of 8 centimeters?
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
How do you figure the area of a circle with radius of 8 cm?
A = Pi(r)2: A circle with a radius of 8 cm has an area of 201.06 square cm.
If the radius of the circle above is 8 cm what is the area of the circle?
Area of circle: pi*8^2 = 64*pi square cm
What is the circumference of a circle with 8 cm radius?
The circumference of a circle with an 8 cm radius is: 50.27 cm
Find the radius and circumference of a circle with an area of 200.96 cm squared?
A circle with an area of 200.96 cm2 has a:Radius of about 8 cmCircumference of about 50.25 cm
If the radius of the circle is 8 cm what is the circumference of the circle?
If the radius of the circle is 8 cm the circumference is: about 50.27 cm (r x 2 x pi = circumference).
How do you find the area of a circle that measures the diameter of 8 cm?
The formula for the area of a circle is: A = pi r2 where r is the measure of the radius. If the diameter of a circle is 8 cm, then the radius is half of that measure or 4 cm. Plug that into the formula and use 3.14 to approximate pi. A = 3.14(4)2 A = 3.14(16) Area is approximately 50.24 square cm.
What is the approximate area of a circle with 16 cm diameteer?
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
What is the diameter of a circle whose radius is 8 cm?
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
What is the area of the circle with a radius of 8?
A circle with a radius of 8 units has an area of 201.06 square units.
What is the area of a circle with a radius of 8 meters?
The area of a circle with a radius of 8 meters is: 201.1 m2
A chord of a circle has length 4.2 cm and is 8 cm from the center of the circle what is the radius of the circle?
To find the radius of the circle, we can use the Pythagorean theorem. The chord divides the circle into two equal parts, each forming a right triangle with the radius. The radius, the distance from the center to the chord, and half the length of the chord form a right triangle. Using the Pythagorean theorem, we have (radius)^2 = (distance from center)^2 + (1/2 * chord length)^2. Substituting in the given values, we get (radius)^2 = 8^2 - (1/2 * 4.2)^2. Solving for the radius gives us a radius of approximately 7.48 cm.
What is the diameter of a circle if the radius is 8 Cm?
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
