How are we supposed to help with this what the heck??
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,
× 7.5 gal = 6031.85789489
Which equals to 6032 gallons rounded up to whole number.
Answer:
Bradely's average speed is 14.4 miles per hour.
Step-by-step explanation:
Average Speed tells the rate at which object is travelling his whole journey.
∴
⇒
⇒
⇒
⇒ Average Speed = 14.4 miles per hour
Thus, Bradely's average speed for traveeling his whole journey is 14.4 miles per hour.
Fountain
A = pi * 10^2
A = 100pi
Garden
A = pi * 200^2
A = 40,000pi
40,000pi - 100pi = 39,900 m^2
