Answer:
351.9 ft³
Step-by-step explanation:
- <em>Volume of cylinder: V= πr²h</em>
<u>Given:</u>
- d= 8 ft ⇒ r= 8/2= 4 ft
- h= 7 ft
<u>Solution:</u>
- V= π*4²*7 ≈ 351.9 ft³ rounded to the nearest tenths

Plug in the number for “n” then solve: minus 1 times 3 then plus 15
Answer:
y=1/3
Step-by-step explanation:
30y=10 y=1/3
Answer:
(D) xy/(x + y)
Step-by-step explanation:
To find r in terms of x and y
Given,
- two resistors with resistances x and y are connected in parallel
- r is the combined resistance of these two resistors
- the reciprocal of r is equal to the sum of the reciprocals of x and y
Then,
1/r = 1/x + 1/y
1/r = (y + x)/xy
Find the reciprocal of both sides
r = xy/(x + y)
The right answer is option (D) xy/(x + y)
