Im not sure but

(sarah + tara)/2 = 8

(20 + tara)/2 = 8

20 + tara = 16

An atrium is being designed to house an exhibit of tropical birds. The atrium must enclose 250,000 cubic feet of space, and the
9966 [12]

The <em>proposed</em> design of the atrium (<em>V < V'</em>) is possible since its volume is less than the <em>maximum possible</em> atrium.

<h3>Can this atrium be built in the rectangular plot of land?</h3>

The atrium with the <em>maximum allowable</em> radius (<em>R</em>), in feet, is represented in the image attached. The <em>real</em> atrium is possible if and only if the <em>real</em> radius (<em>r</em>) is less than the maximum allowable radius and therefore, the <em>real</em> volume (<em>V</em>), in cubic feet, must be less than than <em>maximum possible</em> volume (<em>V'</em>), in cubic feet.

First, we calculate the volume occupied by the maximum allowable radius:

<em>V' =</em> (8 · π / 3) · (45 ft)³

<em>V' ≈</em> 763407.015 ft³

The <em>proposed</em> design of the atrium (<em>V < V'</em>) is possible since its volume is less than the <em>maximum possible</em> atrium. \blacksquare

Am I right ? Because I need help with this please thanks.
bazaltina [42]

to find the hypotenuse (or the ramp in question 4) you can use the equation

a^{2} +b^{2} =c^{2}

with a and b being the 3 feet and 9 feet and c being the unknown (ramp).

So if you plug 3 and 9 into the equation, it looks like this.

3^{2} +9^{2} =c^{2}

then square them.

9+81=c^{2}

simplify.

90=c^{2}

take the square root of both sides.

\sqrt{90} = c

\sqrt{90} is approx. 9.5 so the answer would be H.
