Question

if the diameter of a sphere is 7 cm then the radius is​

Answer 1

Answer:

radius of sphere is 3.5 cm

Answer 2

Given:

If the diameter of a sphere is 7 cm then the radius is​?

To find:

The radius

Solution:

We know that,

Diameter: A diameter of a circle is any straight line that passes through the centre of the circle and whose endpoints lie on the circumference of the circle.

Radius: A radius of a circle is any straight line that is formed by joining the centre and any point on the circumference of the circle.

So, we can say that

$\boxed{\bold{Radius = \frac{1}{2} \times Diameter}}$

Here we have

The diameter of the sphere = 7 cm

∴ The radius of the sphere is

= $\frac{1}{2} \times 7$

= $\bold{3.5\:cm}$

Thus, the radius is​ → 3.5 cm.
