Answer:
500π ≈ 1570.796
Step-by-step explanation:
diameter = 10
radius = diameter / 2 = 10 / 2 = 5
height = 4 * radius = 4 * 5 = 20
volume = π * height * (radius)² = π * 20 * (5)² = 500π ≈ 1570.796
Answer:
1570.8 in ^3
Step-by-step explanation:
The radius of a circle is simply half the diameter so the radius is 5.
10/2=5
Therefore, the height is 20
4x5=20
The formula for the volume of a cylinder is πr^2h
π = π
r= radius
h=height
so π(5)^2(20) = 1570.796327 in ^3
for sig figs, 1570.8 in ^3
hope this helps :)

Answer:
100 grams.
Step-by-step explanation:
600-(10*50). You're subtracting the weight of 10 mangoes (50 grams for each mango) from 600 grams, which will give you the weight of the basket.
3,843,000. the number next to 2 (which is in the thousands place) is 5. so we add one and it became 3,843,000
