Ames was supposed to measure the circumference of three trees as homework for science class. When he got to class the next day, he realized that he measured the trees in inches instead of centimeters.

One tree had a circumference of 17 inches. What is the tree's circumference in centimeters?

Hint: 1 inch equals 2.5 cm

A.

42.5 cm

B.

7 cm

C.

11 cm

D.

56 cm

The tree's circumference in centimetres is 42.5 cm

Step-by-step explanation:

In this question, we are tasked with correcting the measurement error made by Ames.

This is a direct question that we can deal with in a simple fashion. All the question is asking us is to make a unit conversion from inches to centimetre

From the question, 1 inch = 2.5 cm

Thus,  17 inch = x cm

x cm = (17 inch × 2.5 cm)/1 inch

x cm = 42.5 cm

b.an increase in a causes b to decrease
