Either enter an exact answer in terms of or use 3.14 for 7 and enter your answer
as a decimal.

The circumference of the circle is 31.42

Step-by-step explanation:

use 2πr to find the circumference of a circle. since you know the radius is 5, put the 5 were the r is and put the formula into a calculator.

2π(5) = 31.42

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
