Find the cost of polishing of a circular table top of diameter 1.6 m i

1.	Find the cost of polishing of a circular table top of diameter 1.6 m if the rate of polishingis rupees 15 per meter square.
Answer» ANSWER: RS 30.15 Step-by-step explanation: Radius of table = diameter/2 = 1.6/2 = 0.8 m Area of the table = πr² = (22/7) (0.8 m)² [π = 22/7] = 2.01 m² Cost = Rate x area = Rs 15 x 2.01 = Rs 30.15

Find the cost of polishing of a circular table top of diameter 1.6 m if the rate of polishingis rupees 15 per meter square.

Answer»

RS 30.15

Step-by-step explanation:

Radius of table = diameter/2 = 1.6/2

= 0.8 m

Area of the table = πr²

= (22/7) (0.8 m)² [π = 22/7]

= 2.01 m²

Cost = Rate x area

= Rs 15 x 2.01

= Rs 30.15
