Dr.Casey has a cylindrical beaker he fills with about 113 cubic inches of hydrochloric acid. The hydrochloric avid has a height
GREYUIT [131]

Answer: the diameter of the hydrochloric acid in Casey's container is 6 inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylindrical beaker.

h represents the height of the cylindrical beaker.

π is a constant whose value is 3.14

From the information given,

Volume cylindrical beaker = 113 cubic inches.

Height = 4 inches

Therefore,

113 = 3.14 × r² × 4

113 = 12.56r²

r² = 113/12.56 = 8.9968

r = √8.9968

r = 3

Diameter = 2 × radius

Diameter = 2 × 3 = 6 inches
