Evaluate the following formula for a=13 inches, b=7.2 inches, and c=3.7 inches.
P= a+b+c, where P is the perimeter of a triangle with sides a, b, and c
P= how many inches?

Step-by-step explanation:

Formula Evaluation

Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.

Formulas are usually expressed as mathematical operations that connect one or more variables.

The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula

We are given the values of

Thus the perimeter is

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

once you solve it out the value of x is 13
