Answer:
546
Step-by-step explanation:
The lateral area is made up of 4 faces that do not includes the bases.
2 faces have dimensions 2.5 ft by 21 ft.
2 faces have dimensions 10.5 ft by 21 ft.
LA = 2 * 2.5 ft * 21 ft + 2 * 10.5 ft * 21 ft
LA = 105 ft^2 + 441 ft^2
LA = 546 ft^2
Answer: 546
I believe f(5) is the number f equals hope that helped
V (cube)=9³=729 cm³
V (cone)=1/3*π*R²*H= 1/3*π*3²*9=84.8 cm³
V (metal)= 729-84.8=644.2 cm³
Answer:
∠C = 37° ,
AB = 26.54 cm ,
BC= 33.27 cm
Step-by-step explanation:
Given that in triangle ABC
∠A = 39° AC = 20 cm
∠B = 104°
∵ sum of all the three angles of triangle = 180°
So, ∠C = 180° - ( ∠A + ∠B)
∠C = 180° - (39° + 104°)
∠C = 37°
Now Tan 37° = ![\frac{AC}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BAB%7D)
Or, AB = ![\frac{20}{tan 37°}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7Btan%2037%C2%B0%7D)
So, AB = 26.54 cm
Again, Sin 37° = ![\frac{AC}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D)
So, BC = ![\frac{20}{sin 37°}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7Bsin%2037%C2%B0%7D)
Or, BC = ![\frac{20}{0.601}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B0.601%7D)
∴ BC= 33.27 cm
Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
Choose the most appropriate unit to measure the weight of each.
Write oz., lb., or T.
#1. Car = T
#2. Computer = lb.
#3. Bowling Ball = lb.
#4. Onion = oz.
#5. Tyrannosaurus Rex = T.
#6. Vacuum Cleaner = lb.
#7. Q. A hippo weighs about 5,000 lb.. Does the same hippo weigh more or less than 5,000 oz.?
A. If one ounces is 0.0625 pounds then 5000 ounces are 312.5 pounds so the same hippo weighs more than 5,000 oz.
