Answer:
251.33in²
Step-by-step explanation:
A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
We solve the above question using the formula for Total surface area of a cylinder.
TSA = 2πr (h + r) Square units.
Where
h = Height of the cylinder
r = Radius of the cylinder
Diameter of the container is 10 inches
Hence, radius = Diameter/2 = 10/2 = 5 inches
Height is 3 inches.
Hence, Total surface area =
2 × π × 5 (5 + 3)
= 10π × (8)
= 251.32741229 in²
Approximately = 251.33 in²
Therefore, the amount of sand that can fit into the cylinder = 251.33 in²

yousearch up how do u solve the square root of 258.75
X: 90 degrees. y: 43 degrees
We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.
20 + (34*10) = 360
320-360=40
(40/320)*100 = 12.5
12.5 / 10 = 1.25
1.25 * 12 = 15%
Hope this helps! :)
Answer:
36 inches of cable weighs 0.68 lbs
Step-by-step explanation:
1178 ft cable weighs 266 lbs...and u want to know how many lbs a 36 inch cable weighs....
we need to turn ur ft to inches....1 ft = 12 inches....so 1178 ft = (1178 * 12) = 14,136 inches
14136 in. to 266 lbs = 36 in.to x lbs
14136 / 266 = 36 / x...cross multiply
14136x = (36)(266)
14136x = 9576
x = 9576 / 14136
x = 0.6774 rounds to 0.68 lbs <===
