Answer:
6032 gallons
Step-by-step explanation:
The diameter of the cylindrical swimming pool is 16 ft
The height(h) of the pool is 4 ft
Volume of a cylinder is given by;
Volume (v) = π × r² × h
Radius (r) = 16/2 ft = 8 ft
v = π × (8 ft)² × 4ft = 804.247719319ft³
Given; 1ft³ = 7.5 gallons (gal)
804.247719319ft³ would equal to how many gallons?
Cross multiplying gives,
[tex]\frac{804.247719319}{1}[/tex] × 7.5 gal = 6031.85789489
Which equals to 6032 gallons rounded up to whole number.
Answer:
107 gal
volume formula of a cylinder is pi * r^2 * h
it gives you the diameter 16 but we need to find the radius. divide it by 2. radius is 8
we already know the height.
pi= 3.14 * 8^2 * 4
3.14 * 64 *4
you find your volume. then divide it by 7.5
