Question

In a grass field, a bull is tied to a pole with a rope of length 7 meters. How much area of field is it allowed to be grazed?
$(Take\pi =\frac{22}{7}$)

• A. 154 $m^2$
• B. 110 $m^2$
• C. 55 $m^2$
• D. 100 $m^2$

Answer 1

The correct option is A

154 $m^2$

Area of field allowed to be grazed

= Area of circle of radius 7 m

$=\pi r^2$

$=\frac{22}{7}\times 7\times 7$

$=154m^2$
