Answer: 5.64 units

Step-by-step explanation:

The volume of a cylinder is given by :-

\text{Volume}=\pi r^2 h, where r is radius and h is height of the cylinder.

Given : Volume of cylinder = 175 cubic units

Height = 7 units.

Substitute these values in the above formula , we have

175=(3.14) r^2 (7)\\\\\Rightarrow\ r^2=\dfrac{175}{(3.14)(7)}\\\\\Rightarrow\ r^=7.96178343949\\\\\Rightarrow\ r\approx2.82

Now, the diameter of the cylinder will be given by :-

d=2(2.82)=5.64\text{ units}

4) How many km in<br> 58,795cm?<br><br><br> Please help thanks!!
Leto [7]

Step-by-step explanation:

1 km is equal to 100,000 cm.

58,795 is close to 50,000, which is half of 100,000. So our estimate would be 1/2 km to 50,000 cm.

Convert 58,795 to a decimal.

0.58795

The decimal cannot be simplified so there is

0.58795 km in 58,795 cm

Hope it helps!

Solve for x.<br> 3(x - 4) = 2x + 6<br> Α. Ο<br> B. 2<br> C. 3.6<br> D. 10<br> E. 18
LekaFEV [45]
3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)

Therefore, we know that x is equal to 18, and so the answer is E.

A sail is in the form of a right triangle that is two times as high as it is wide. The sail is made from 4 square meters of mate
Ivahew [28]
<h3>Answer:</h3>

4 m

<h3>Explanation:</h3>

If we let h represent the height of the sail, then its width is h/2. The area of the sail is given by ...

... A = (1/2)wh

Filling in the given information, we have

... 4 m² = (1/2)(h/2)h

... 16 m² = h² . . . . . . multiply by 4

... 4 m = h . . . . . . . . take the square root
