Gre4nikov [31]

Answer:

18 inches and 9 inches

Step-by-step explanation:

Given, The base of a triangle is twice of the height.

Area = 81 sq inches

Let, Base (b) = 2x

Height (h) = x

Area of the triangle = \frac{1}{2}bh

\frac{1}{2}bh = 81

or, x^{2} = 8

Base = 2×9 inches = 18 inches

Someone help me I don’t understand the circumference C=2TTr

Irina-Kira [14]

You are being asked to make π the subject in

$C=2πr \:$

So divide both sides of the equation by
$2r$

That is

$\frac{ C}{2r} = \frac{2πr}{2r}$
The you have
$\frac{ C}{2r} = \pi$

or

$\pi = \frac{ C}{2r}$

I hope this is helpful?
