Solve the equation for the bold variable (h)

Aleonysh [2.5K]

This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.

S = 2·π·r² + 2·π·r · H

Divide each side by 2·π·r :

S/2·π·r = r + H

Subtract r from each side :

H = (S/2·π·r) - r

H = (S - 2·π·r²) / (2·π·r)

Which side lengths form a right triangle

aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

A right triangle consists of two legs and a hypotenuse.
To find hypotenuse, we use The Pythagorean Theorem
The Pythagorean Theorem = ${a}^{2} + {b}^{2} = {c}^{2}$
two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

${5}^{2} + { \sqrt{6} }^{2} = { \sqrt{31} }^{2}$

Option A is correct

${5}^{2} + {5}^{2} = { \sqrt{50} }^{2}$

But B isn't correct

Hope this helps ^-^
