Answer:

30.54

Step-by-step explanation:

Here is the complete question used in answering this question

he given cylindrical container r =3 inches and height= 8in is used to fill the rectangular prism fish tank 24 , 24 and 12 inches with water. What is the least number of full cylindrical needed to completely fill the fish tank?

Number of cylinders needed = volume of prism / volume of cylinder

volume of prism = width x height x length = 24 x 24 x 12 = 6912

volume of a cylinder = nr^2h

n = 22/7

r = radius

(22/7) x (3^2) x 8 = 226.29

6912 / 226.29= 30.54

Find principal of a loan at 11% for 5 years with $426.25 simple interest
Ahat [919]

Answer:

P=775

Step-by-step explanation:

The Simple Interest Equation is A = P(1 + rt)

where

A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

t = Time Period involved in months or years

In this case, we do not know the values ​​of the equation (A and P), but we know the amount of interest accrued

If we define our principal whit this formula, we are able to know the rest of the values:

A-P= interest

clearing

A=interest+P

replacing

426.25 + P = P (1+(0.11(5))

Solving

426.25+P=1.55P

P-1.55P=-426.25

-0.55P=-426.65

P=\frac{-426.25}{-0.55}

P=775
