The volume (in cm3^33​) of a wire of diameter 10 cm and length 28 m is: take π=227\pi = \frac {22}{7}π=722​​
Question

The volume (in cm3^3​) of a wire of diameter 10 cm and length 28 m is: take π=227\pi = \frac {22}{7}

A.

221000

B.

220500

C.

220100

D.

220000

Correct option is D

Given:

Diameter of wire = 10 cm

Radius (r) = 5 cm
Length or Height (h) = 28 m = 2800 cm

Formula Used:
Volume of cylinder = πr²h

Solution:
Volume =227\frac{22}7​× (5)² × 2800

= (22×25×2800)7\frac{(22 × 25 × 2800) } 7​​
= 22 × 10,000
= 2,20,000 cm³
