Answer:
SA = 967.6 cm²
Step-by-step explanation:
Surface Area of cylinder =
<u><em>Where r = 7 cm, h = 15 cm</em></u>
=> SA = 2(3.14)(7)(15)+2(3.14)(7)²
=> SA = 659.7 + 2(3.14)(49)
=> SA = 659.7 + 307.9
=> SA = 967.6 cm²
The square's diagonal is the triangle's hypotenuse.
the original Pythagorean theorem is
where
a and
b are the two sides and
c is the hypotenuse.
that means the Pythagorean theorem for this question is:
or
The reflection across y axis of (x,y) would be (-x,y)
thus the answer is b
