Question

please answer my question ​

Answer 1

Step-by-step explanation:

Fencing is done around the park so we need to find the perimeter

Perimeter of Circle =2πr

r=21/2 as radius is half of diameter (we will use it in fraction as it will we easy for calculation).

2×π×r

π=22/7 (if π value is not given in ques we use π=22/7)

2×22/7×21/2

as it is given that fancing is done twice so we will do twice the perimeter

2×21/2×22/7×2 = 132 m

cost is 4rs per m

total cost = 132*4

528 rs

is the total cost
