the radius of a circular gardend is 8.75 cm how much wold it cost to put a five round fence around the garden at the rate of rupees 12 per meter
Answers
Answer:
Given radius of circular garden =56m
Perimeter of garden =2πr=2π×56
Perimeter =112πm
Now for four rounds =112π×4
4 perimeter =448πm.
Cost of fencing =40 Rs./m
Total cost of fencing =40×448π
=17920πRs.
Total cost =56,267.8 Rs.
Total cost of fencing is 56,268.8 Rs.
Answer:
3,300 rs.
Step-by-step explanation:
Radius of the circular garden, r = 8.75 m
Circumference of the circular garden, c = 2πr
= 2 x 22/7 x 8.75
= 55 m
Length of the wire needed for one round of fencing=c = 55 m
Cost of one round of fencing = length of wire x cost per metre. = 55 x 12
= 660 rupees
Cost of five rounds of fencing = 5 x 660 = 3300
= 3,300 rupees
