Question

What is the cost of fencing a circular garden of radius 35 m with four rounds of wire, u the wire costs 44 per metre? (1) 38.720 (2) 38.730 (3) 38.740 (4) 38.750​

Answer 1

Step-by-step explanation:

perimeter of the garden pai×35^(2)

22/7×35^2

total cost 22/7×35^2×44

Answer 2

Answer:

$\sf{Radius \: of \: circular \: garden = 35 \: meter}$

$\sf{Rate \: of \: fencing = 16 \: per \: meter}$

$\sf{Circumference \: of \: circle = 2πr}$

$\sf{Where, r = radius \: of \: circular \: garden}$

$\sf{π = } \frac{22}{7}$

$\sf{Circumference = 2πr}$

$\sf{⇒ 2 × } \frac{22}{7} \times \: 35$

$\sf{⇒ 220 m}$

$\sf{⇒ Total \: cost \: of \: fencing = rate \: \times circumference}$

⇒ 16 × 220

∴ Rs 3520
