Answer:

i think its 2,080

Step-by-step explanation:

the diameter is 40ft and the radius r=\frac{40}{2}=20ft and height is h=32ft.

A=2pi(20)(20+32)=40pi52=2,080pi square ft

How do you write the equation of the horizontal line passing through (1,9)?
Leviafan [203]

he equation of any horizontal line is

y = .. a number

The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.

In this case the line passes though the point (−8,9)

which tells us that the y-value we want is 9.

Therefore the equation is y=9

HELP!!!! Order the lengths of the sides of ABC from greatest to least
azamat

The comparison of the lengths of the sides based on the angles are given

by sine rule.

The lengths of the sides from greatest to least are;

  • <u>BC > AC > AB</u>

Reasons:

The given parameters are;

∠A = 78°, ∠B = 56°, ∠C = 46°

By sine rule, we have;

\displaystyle \frac{AC}{sin(56^{\circ})} = \frac{AB}{sin(46^{\circ})} = \frac{BC}{sin(78^{\circ})}

Given that, sin(46°) ≈ 0.719, sin(56°) ≈ 0.829, sin(78°) ≈ 0.978, we have;

sin(78°) > sin(56°) > sin(46°)

Therefore, applying equal proportions of similar ratios, we have;

<u>BC > AC > AB</u>
