The volume of a cylinder is 252π cm3 and its height is 7. What is the cylinders radius?
stiks02 [169]
The volume of a cylinder is given by the formula;
Volume = πr²h, where r is the radius, and h is the height or the length 
Therefore,
252 π cm³ = π r² (7)
           r² = 252/7
              = 36
            r = √36
               = 6 cm .
Hence, the radius of the cylinder is 6 cm

What is the length of the altitude to the longest side of a triangle, if the lengths
sergeinik [125]

Answer:

hb ≈ 7.06cm

Step-by-step explanation:

Using the formulas:

A=hbb

2

A=s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c

2

Solving for <em>hb</em>

hb=﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

2b=﹣154+2·(15·17)2+2·(15·8)2﹣174+2·(17·8)2﹣84

2·17

≈7.05882cm

Can someone help me with this
Thepotemich [5.8K]

Answer:

D: 1/35

Step-by-step explanation:

First, you have to know how many marbles there are, and if you count them all up there are 15 marbles in total. Next, there are 3 blue marbles, so you would put the fraction as 3/15, or simplified to 1/5. Now, if you don't replace that blue marble, you now only have 14 marbles, and there are 2 yellow, which means you have a 2/14 chance of drawing a yellow marble, simplified to 1/7. But because there are two parts of the problem you are going to multiply 1/5 by 1/7 to get 1/35, which is your answer.
