Question

the distance covered by the wheel in 500 revelutionsis 1980m .find the area of the wheel
ans this easy question fast
be careful while answering otherwise ans will be reported

Answer 1

Answer:

Step-by-step explanation:

Circumference of circle = 2πr

Radius of Circle = (77/2)

Now, Putting the Values,

2×22/7×77/2 = 242

That means 1 revolution = 242

then, 500 revolution = 242×500

= 121000

SO THE DISTANCE COVERED BY THE WHEEL= 121000.

Answer 2

Answer:

number of revolutions = 500

distance covered by wheel = 1980m

circumference of wheel = distance covered / no. of revolutions

= 1980/500 = 19.8/5 = 3.96 cm

circumference = 3.96cm

2 pi r = 3.96cm

r = 3.96 * 7 / 22 *2 = 0.06 * 7 = 0.42cm

area of wheel = pi r^2

= 22/7 * 42/10 *42/10 = 55.44cm²
