33. A circular plot of land is of
radius 49 m. A path 3.5 m
wide needs to be paved around
this plot. Find the cost of
paving this path at the rate
of 30 per sq. m.
​

First the total circle area of radius 49 m is

= 22/7 × 49 × 495

= 7546 sq.m

Next, the circle without the path with radius 49 - 3.5 = 45.5

= 22/7 × 45.5 × 45.5

= 6506.5 sq.m

Area of path = Big circle area - small circle area

= 7546 - 6506.5

= 1039.5 sq.m

Cost of paving the path = 1039.5 × 30

= Rs. 31,185

Therefore, Rs 31185 is needed to pave the path

answer:

step-by-step explanation:

each hour has 60 minutes

because the number of minutes in an hour is fixed at 60, you can convert any number of minutes into a fraction of an hour by dividing it by 60. for example, 10 minutes is 10/60 = 1/6 of an hour, and 24 minutes is 24/60 = 6/15 of an hour.
