The area of a circle is 9pi cm². Find its radius. <br>Please do this question with full solution:)​
kirill115 [55]

Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

A = \pi r^2

Where "r" represents the radius of the circle. We can substitute the given value for Area into the equation to solve for the radius.

<h3>Solve for Radius</h3>

A=\pi r^2\\9\pi = \pi r^2

Divide both sides by π

9=r^2

Take the square root of both sides

\sqrt9=\sqrt {r^2}\\r=3

The radius of the circle is 3 cm.

Jeff put a small box that is 12 inches long, 8inches wide, and 4 inches tall inside a box that is 20 inches long, 15 inches wide
lesya692 [45]
Formula 

V is H×L×W
small box details are 12 inches long, 8 inches wide, and 4 inches tall therefore using the formula given, 12 × 8 × 4 gives you 384 inches ³
big box details are 20 inches long, 15 inches wide, and 9 inches high there using the formula given, 20 × 15 × 9 gives you 2700 inches ³
cubed to the 3rd? because there are 3 numbers instead of 2
so, you're left to subtract with what you gotten 2700 - 384 gives you 2316 inches cubed. hope that was helpful
