Awindscreen wiper of a vehicle of length 30 cm clears out an angle of 180 degrees what is the area of the screen cleared take pie=22/7

Therefore the area of the screen cleared is 1414.28 cm².

Step-by-step explanation:

Given:

a windscreen wiper of a vehicle of length 30 cm

Consider this length as Radius of Semicircle, r = 30 cm

clears out an angle of 180 degrees implies Semicircle Shape

pie=22/7

To Find:

Area of the screen cleared

= ?

Solution:

We have

Substituting r and pie we get

Therefore the area of the screen cleared is 1414.28 cm².

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
