Find the radius of a circle whose diameter is 7 inches?
Radius = 1/2 of diameter = 7/2 = 3.5 inches
What is the length of the radius to the length of the diameter?
Diameter divided by 2 equals radius r=d/2 For example, if the radius was 3.5, the diameter would be 7.
How do you get the circumference when you have the radius?
Multiply 2 times pi (3.14 OR 22/7) times the radius 2(pi)r
Which is an equation of a circle with center ( 2 7 ) and radius 4?
It is: (x-2)^2 +(y-7)^2 = 16
What is the equation of a circle with center -7-2 and radius 4?
It is (x + 7)2 + (y + 2)2 = 42
What is the radius of a circle with a diameter of 7 over 8?
7 over 16
Does the radius of a circle measure 14 feet if the diameter is 7 feet?
No. diameter = 2 x radius ⇒ radius = diameter ÷ 2 If the radius is 14 ft the diameter is 2 x 14 ft = 28 ft If the diameter is 7ft the radius is 7 ft ÷ 2 = 31/2 ft.
If the diameter is 14 What is the radius?
The radius of a circle is half the diameter.
What is the volume of a cylinder with a radius of 2 meters and a height of 7 meters?
A cylinder with a radius of 2 meters and a height of 7 meters has a volume of 87.96 cubic meters.
The diameter of a circle is 14 meters what is the radius?
Radius of circle: 14/2 = 7 meters
Is the area of a circle of radius 14 units equal to the surface area of a sphere of radius 7 units?
surface_area_sphere = 4 × π × radius_sphere² = π × (2 × radius_sphere)² area_circle = π × radius_circle² These are equal when: π × radius_circle² = π × (2 × radius_sphere)² → radius_circle² = (2 × radius_sphere)² → radius_circle = 2 × radius_sphere As the given circle has a radius of 14 units and the given sphere has a radius of 7 units, and 14 = 2 × 7, it is true that the area of a circle with a radius of 14 units is the same as the surface area of a sphere with a radius of 7 units.
What is the circumference of a 15 feet diameter circle?
47.14285714285714 radius = 1/2 of diameter radius=7.5 which is half of 15 using circumference of circle formula (2 * by pi * by radius) pi=22/7 2*22/7*7.5=47.14285714285714
What is the circumference of a circle with a radius of 7 and 3 for pi?
Circumference of a circle = 2*pi*radius or diameter*pi
What is the circumferance of a seven eighths inch circle?
7/8 inch circle has a diameter of 7/8 and a radius of 7/16=.4375 circumferance of a circle = 2*pi*radius = 2*3.14*.4375 =2.7475 or 7*pi/8
What is 2 over 7 - 4 over 7?
negative 2 over 7
What is the perimeter of a circle if the radius is 7 m?
perimeter or circumference = 2*pi*7 m
What is the lateral area of a cylinder that has a radius of 4 in and a height of 2 in?
7
