The circumference of the circle in terms of pi, based on the area of the circle is 6 π.
<h3>How to find the circumference?</h3>
The area of a circle can be found by the formula:
= π x radius x radius
= π x radius ²
If the area of the circle is 9π cm², then the radius is:
= √9π cm²
= 3 π cm
The diameter of a circle is double the radius so the diameter is:
= 3 x 2
= 6 cm
The circumference of a circle is:
= π x diameter
= π x 6
= 6π

Answer:
7 minutes
Step-by-step explanation:
When Rob climbed the Eiffel Tower today, he climbed 1,000 steps in 25 minutes.
Today
Steps : minutes = 1000 : 25
If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow
Let x = number of minutes it will it take Rob to climb the stairs tomorrow
Tomorrow
Steps : minutes = 280 : x
Equate both ratios
1000 : 25 = 280 : x
1000 / 25 = 280 / x
Cross product
1000*x = 25 * 280
1000x = 7000
Divide both sides by 1000
x = 7,000 / 1,000
= 7
x = 7 minutes
