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

<h3>What is decimal?</h3>

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the term used to describe the method of representing numbers in the decimal system. The base-10 number system, arguably the most widely used number system, is referred to as decimal. The decimal number system consists of ten single-digit numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The number following nine is 10.

Here,

Repeating decimal representation,

=3/13, 7/24

Terminating decimal representation,

=3/16, 4/125

3/13 and 7/24 will be repeated in decimal form. The final two decimal places are 3/16 and 4/125.

Rectangle (left): A = 9 x 7 = 63

Rectangle (right): A = 2 x 10 = 20

Quarter circle: A = (1/4 x 3.14 x 3^2) = 7.065

A = 63 + 20 + 70.65

A = 90.065 square feet

Hope this helps! :)
