Answer 2

Answer:

The radius of the sphere will be 3.5cm if the diameter is 7 cm.

Step-by-step explanation:

1) What is sphere?

3-Dimensional circular solid such that every point on its surface is equidistant from the centre.

2) What is the Diameter of the sphere?

The distance between two points on the surface of sphere such that the line joining them passes from centre.

3) What is the radius of Sphere?

The distance between any point on the surface of sphere and it's centre.

4) Now by the defination of diameter and radius, we can say that diameter is double of radius of the sphere.

5) As the diameter of the given sphere is 7 cm, the radius will be half of it.

radius = diameter/2

$= \frac{7}{2} cm$

$= 3.5 \: cm$

6) Thus the radius of the sphere with diameter 7 cm is 3.5 cm
