Solution-
Capacity of the spherical tank = 800 gallons.
1 gallon = 0.1337 ft³,
Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³
Formula for the volume of sphere

Equating both the volumes
⇒
= 106.96
⇒
= 25.53
⇒ ![r = \sqrt[3]{25.53}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B25.53%7D)
⇒ r = 2.94
∴ Radius of the sphere is 2.94 ft
Answer:
a= 2 b=-1
Step-by-step explanation:
a-3b=5
or, a= 5+3b_(i)
substituting value of a in 2a+b=3,
2×(5+3b)+b=3
or, 10+6b+b=3
or, 7b=3-10
or, 7b=-7
b= -1
substituting value of b in(i),
a=5+3b
=5+3×(-1)
=5-3
=2
120 seconds is 2 * 60s
60s is 1 minute, so 2*60s = 2 minutes
