Question

The diameter of a tyre of a tricycle is $32\text{cm}$. What is the radius of the tyre ?

Answer 1

We know that radius is the half of the diameter i.e., $\mathrm{Radius}=\frac{\mathrm{Diameter}}{2}$ .

So, $\mathrm{Radius}\mathrm{of}\mathrm{tyre}=\frac{32\mathrm{cm}}{2}=16\mathrm{cm}$

Hence, radius of the tyre is $\text{16 cm}$ .
