You multiply radius by 3.14 by the height if you plug it in your equation is 8×3.14×15 which equals 1005.31 which rounds to 1005, the answer is 1005! :D

The perimeter of a rectangular campsite is 64 cm and its area is 207 cm. Find the length and the breadth of the rectangle.

AlladinOne [14]

Perimeter Formula:
$2l + 2b = 64$

Area Formula:
$l \times b = 207$
Set perimeter Formula equal to b:
$2l + 2b = 64 \\ 2(l + b) = 64 \\ l+ b = 32 \\ b = 32 - l$
Plug formula for be we just made above into the area Formula:
$(32 - l) \times l = 207$

Solve for L (you'll have to use quadratic formula) then plug that back into the area Equation and solve for b.

Here's a link to where the problem has been explained before (they go into more detail than me).

The product of four different positive integers is 100. What is the sum of these four integers?

Leno4ka [110]

Step-by-step explanation:

The Answer for the above question is

The four integers are 1,2,5,10. And Sum of the four integers is 18 .

Method :

Product of four different positive integers is 100 .

First of all lets break the number "100"

⇒ 100 = 50*2

⇒ 100 = 25 * 2 * 2

⇒ 100 = 5 * 5 * 2 * 2

But here we get the same integers 2 and 5 and we want different positive integers . So hereby merge 5 * 2 which is 10.

Let's get to the possible combination -

After merging 5*2 = 10 we get the answer as -

⇒ 100 = 1 * 2 * 5 * 10

Here, we have 1, 2, 5, 10. these are the positive integers whose product gives 100 .

Sum of these products is -

⇒ Sum = 1 + 2 + 5 + 10

⇒ Sum = 18 .

Sum of these four Integers is 18.
