The base of a right circular cylinder has a diameter of 5.00 inches. sally measured the circumference of the base cylinder and recorded it to be 15.5 inches. what is the percent of error in her measurement? express your answer to the nearest tenth of a percent.
explain what you did to get your answer!

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

where

D is the diameter

we have

assume

substitute

----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

Find the percentage by proportion

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

i think 1: 2
