One side of a right triangle has a length of 12 feet. Which of the following could be lengths for the two other sides of the rig
Elodia [21]

Answer:

B

Step-by-step explanation:

Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:

I. 5 feet and 13 feet:  5^2 + 12^2 = 13^2 is TRUE

II.  9 ft and √63 ft:  9^2, 63, 12^2:  63 + 81 do add up to 144  TRUE

III.  2, 10, 12^2:  2 + 10 do NOT add up to 144.  FALSE

Answer B is correct

The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.
Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

  • 770 = πr²5

We divide both sides by 5:

  • 154 = πr²

Now we divide both sides by π:

  • 49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

  • 7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Amna
