Answer:

The answer is 28.26 square in

Step-by-step explanation:

As, the diameter if the top = 6 inches

And the area of a circle = 3.14(pi) x radius^2

So here radius = Diameter /2 = 6/2 = 3

So radius = 3 inches

So area = 3.14 x (3)^2

= 3.14 x 9

= 28.26 square in

Deffense [45]
So there are three variables, rs2 label x, rs5 label y, rs10 label z
Lets write equeations using these variables. 
x+y+z=120  (<span>A bag has a total of 120 notes)
2x+5y+10z=760  (total value)
2x+5*2y+10z=960  (twice as many rs5)

3 variables, 3 independent equations will give solution. There are a fair few ways to solve this. </span>

Diameter of wheel of car is 35 cm . how much distance will it cover in 1000 revolution.
kirill115 [55]

Answer: 35000π cm.

Step-by-step explanation:

First find circumference

Circumference = 2 × π × radius

Circumference = 2 × π × ( diameter / 2 )

Circumference = 2 × π × ( 35 / 2 )

Circumference = 35 × π cm

Now,

1 revolution = 1 circumference

1000 revolution = 1000 circumference

1000 revolution = 1000 × (35 × π)

1000 revolution = 35000π cm.
