Answer:

The answer is <em>c</em>

Step-by-step explanation:

If the area of the two triangles are similar, then Area of ∆ 1 : Area of ∆ 2 =

(Side of ∆ 1)² : (Side of ∆ 2)²

____________________________

Since the area of each triangle is equal to the corresponding side squared.

Area of ∆ = (Side of ∆)² →

√(Area of ∆) = Side of ∆ →

Side of ∆ = √(Area of ∆).

Therefore:

9 : 4 → √9 : √4 = 3 : 2

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius o

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have r = 1cm and H = 21cm. Substitute:

$V=\pi(1^2)(21)=21\pi\ cm^3$

The formula of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have V = 21π cm³ and H = 7cm. Substitute:

$\dfrac{1}{3}\pi(r^2)(7)=21\pi$ <em>divide both sides by π</em>

$\dfrac{1}{3}(7)(r^2)=21$ <em>divide both sides by 7</em>

$\dfrac{1}{3}r^2=3$ <em>multiply both sides by 3</em>

$r^2=9\to r=\sqrt9\\\\r=3\ cm$
