Question

the volume of a spherical tank is 3 052.08 m3. ifthe volume formula is 4 n r 3. what is the radius of the tank a.3m b.4m c.6md.9m

Answer 1

Answer:

D. 9 m

Step-by-step explanation:

Given:

• The volume of a spherical tank is 3052.08 m³.
• Formula of volume of a spherical tank = 4/3πr³.

To find:

• The radius of a spherical tanks.

Solution:

Here, we will simply use formula of volume of sphere ( given to us ). Substituting the values in the formula and then doing the basic mathematical calculations we can easily find out the radius of a spherical tank.

♦ Volume of a spherical tank = 4/3πr³

Here,

π = 3.14

r is the radius of a spherical tank which we need to find.

Putting the values in the formula, we have:

• 3052.08 = 4/3 × 3.14 × r³
• 3052.08 = 12.56/3 × r³
• r³ = 3052.08 × 3/12.56
• r³ = 305208/100 × 3/1256/100
• r³ = 305208 × 3/1256
• r³ = 38151 × 3/157
• r³ = 243 × 3
• r³ = 729
• r = ³√729
• r = 9 m
