The question "how much space is inside a solid?" is actually asking about the volume of that solid.

The volume of a cone is given by

V = \dfrac{1}{3}\pi hr^2

where h is the height of the cone, and r is its radius.

So, you only need to plug in the values:

V = \dfrac{1}{3}\pi\cdot 50 \cdot 200^2 = \dfrac{2000000\pi}{3}m^3

A rectangle has an area 18sq cm.id its length and width are wjole numbera.what is its greatest possible perimeter
makkiz [27]

Answer:

38cm

Step-by-step explanation:

1. The perimeter of a square can be found with the formula2 \times (width + length)

2. Since its length and width are whole numbers, it must be either

1 x 18,

2 x 9 or

3 x 6

3. Using the formula in step 1, we can found that the perimeter in these cases are

38

22

18

respectively

4. Compare those perimeter we found in previous step, it's obvious that the greatest is 38. Solved.

ehidna [41]

Answer:

 (x - 8)^2 + y^2 = 3.

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

Here h = 8, k = 0 and r^2 = (√3)^2 = 3

The answer is  (x - 8)^2 + (y - 0)^2 = 3

or (x - 8)^2 + y^2 = 3.

What is 26.99 round to the nearest tenth
Arte-miy333 [17]
Salutations!

To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.

<span>26.99 round to the nearest tenth </span>≈ 27

Hope I helped (:

Have a great day!
