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
or
H = (S - 2·π·r²) / (2·π·r)
Grace’s because she followed the order of operations. Addition and subtraction first, then multiply and divide.
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 =

- 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

Option A is correct

But B isn't correct
Hope this helps ^-^
Answer:
54
Step-by-step explanation:
There's 27 2's, so 27 * 2 = 54. Note that multiplication exists for a reason: to avoid expression's where there's an absurd number of +'s.
