Answers
Answer:
hey your answer is as follows
so pls mark it as brainliest
Step-by-step explanation:
now here area of circular garden=area of circle
so here radius of circular garden(r)=10 cm
thus then
area of circular garden=pi×r square
put pi=3.14 for easy calculation
so thus we get
=3.14×10×10
=3.14×100
=314
hence area of circular garden=314 cm.square
so thus then
cost of fencing the whole garden=cost of fencing per meter×area of garden
=314×11
=3454 Rs
hence cost of fencing the circular garden of radius 10cm at the rate of 11Rs per meter is 3454 Rs
Answer:
The circumference of circular garden = 2πr
=> 2 × 22/7 × 10
=> 62.8m
.°. cost of fencing garden= rs. 11 × 62.8 = Rs. 690.8
Note:
It's not necessary to find out the area of the circular garden but the circumference of the circular garden is required to know because, we need to know the cost of fencing around a circular garden.
