Elena L [17]

Answer:

V ≈ 7186 in³

Step-by-step explanation:

The volume of a cone of base radius r and height h is V = (1/3)(π)(r^2)(h).

When h = 15 in and r = 12 in, the volume of the cone is

V = (1/3)(π)(12 in)²·(15 in), or approximately V ≈ 7186 in³

Ram gained 25 percent by selling a second hand motorcycle for Rs. 45000. At
scZoUnD [109]

Answer:

Ram bought that motorcycle for Rs. 36000

Step-by-step explanation:

Given that:

Amount gained = 25%

Selling price of motorcycle = Rs. 45000

As 100% will be the original price, then 25% will be added into it.

125% will be the new percentage.

Let,

x be the original price of motorcycle.

125% of x = 45000

\frac{125}{100}x=45000

1.25x=45000

Dividing both sides by 1.25

\frac{1.25x}{1.25}=\frac{45000}{1.25}\\

x=36000

Hence,

Ram bought that motorcycle for Rs. 36000
