The diameter of circle X is 15 centimeters. The diameter of circle Y is 20 centimeters. Which measurement is closest to the diff
valina [46]

The difference between the circumference of circle X and circumference of circle Y is 5π cm.

<h3>What is circumference of a circle?</h3>

This is the distance round a circle.

The circumference of circle X is calculated as follows;

C_X = \pi d\\\\&#10;C_X = 15\pi \ cm

The circumference of circle Y is calculated as follows;

C_Y = \pi d\\\\&#10;C_Y = 20 \pi \ cm

The difference between the circumference of circle X and circumference of circle Y is calculated as follows;

C_Y - C_X = 20\pi - 15 \pi = 5\pi \ cm \\\\&#10;

Thus, the difference between the circumference of circle X and circumference of circle Y is 5π cm.

Nestor works at a garden center where he posts plants. It takes him 2 1/2 hours to pot 15 plants. How many plants can Nestor pot
guapka [62]

Answer:

Nestor can pot 6 plants in 1 hour.

Step-by-step explanation:

first lets convert 2 1/2 hours in mixed fraction form for better calculation

2 1/2 hours = (2*2 + 1)/2 = 5/2 hours

no of plants pot in  5/2 hours = 15

to find no. of plants pot in 1 hours lets

divide both side by 5/2

no of plants pot in  5/2/(5/2)  hours = 15/(5/2) = 15*2/5 = 6

no. of plants pot in 1 hour = 6

Thus, Nestor can pot 6 plants in 1 hour.
