Question

A rope by which a calf is tied is increased from 12m to 23m . how much additional grassy ground shall it graze


please give me easy answer of this question

Answer 1

Answer:1208.9 m^2

Step-by-step explanation:

Given,

Old radius(r)=12 m

New radius (R)=23 m

Old area=pi×r^2=3.14×12×12=452.16 m^2

Increased area =pi×R^2=3.14×23×23=1661.06 m^2

Therefore additional grassy ground =1661.06 m^2 - 452.16 m^2

=1208.9 m^2
