Question

Diameter of a football is $28cm$. It is made up of small hexagones each of area $112c{m}^2$. Find the number of small hexagones used in football.

• A. $21$
• B. $27$
• C. $23$
• D. $22$

Answer 1

Answer: (D)

$22$

Given, diameter of football $=28cm$.

Then, radius of football $=14cm$.

$\therefore$ Area of football $=4\pi r^2=4\times \frac{22}{7}\times 14\times 14=2464{cm}^2$.

Given, area of each hexagon $=112{cm}^2$

Number of hexagon $=\frac{2464}{112}=22$.

Hence, option $D$ is correct.
