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:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
