Q11. - Geometry

Question

What is the radius of sphere with diameter $14,13,5.6,6n$.

Step-by-Step Solution

Answer

If diameter is $14$ then radius is $7$.

If diameter is $13$ then radius is $6.5$.

If diameter is $5.6$ then radius is $2.8$.

If diameter is $6n$ then radius is $3n$.

Step 1. Given information.

Diameters are $14,13,5.6,6n$.

Step 2. Concept used.

Diameter is the twice the length of the radius.  

Step 3. Find the radii.

$radius=\frac{diameter}{2}$

Therefore, If diameter is $14$ then radius is $7$.

                  If diameter is $13$ then radius is $6.5$.

                  If diameter is $5.6$ then radius is $2.8$.

                  If diameter is $6n$ then radius is $3n$.
