Question

The diameter of asphere is measured to be 5.36 in.find the radius of the sphere in centimetres

Answer 1

The radius of any circle or sphere is 1/2 of the diameter.

That's a definition.

If the diameter is 5.36 inches, then the radius

is (5.36/2) = 2.68 inches.

Answer 2

Radius= 6.8072 cm

Step-by-step explanation:

In geometry, the diameter is the line segment that passes through the center and joins two opposite points of a circle or an asphere , and the radius is the distance from the exact center of the sphere to a point on the outer edge.

By definition

`d=2*r\\r=(d)/(2)`

`r=(5.36 in)/(2\\) \\r=2.68 in`

now we convert from inch to centimeter

`2.68 in *((2.54 cm )/(1  in))=2.68*2.54 cm \\ Radius= 6.8072 cm`

I hope it helps you

Have a great day.
