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
Answer:
2/7
Step-by-step explanation:
12 : 42 is the same as 12/42
simplify the fraction by dividing the numerator and denominator by 6
you get 2/7
Less than 45° F is potentially hazardous food.
The volume of a pyramid is one-third of the product of its altitude and area of the base.
Area of the base = (8 in)² = 64 in²
Altitude:
The altitude is the length of the right triangle formed from the base and the slant height as the hypotenuse.
(5 in)² = h² + (4 in)²
h = 3 in
Volume:
V = Ah/3
V = (64 in²)(9 in) / 3 = 192 in³
The volume of the solid right pyramid is equal to <em>192 in³</em>.
