The equation for surface area is: $A= \pi r(r+ \sqrt{h^2+r^2}$ . To get r, you must use Pythagorean theorem. r is found to be 45. This means after you plug it in, you get about 13571.68

The area of the square adjacent to two sides of a right triangle are 29.25 square units and 13 units 30 POINTS

Answer:

$x=6.5\ units$

Step-by-step explanation:

step 1

Find the length side of the smaller square

The area of the square is equal to

$A=a^{2}$

$a^{2}=13$

$a=\sqrt{13}\ units$

step 2

Find the length side of the larger square

The area of the square is equal to

$A=b^{2}$

$b^{2}=29.25$

$b=\sqrt{29.25}\ units$

step 3

Find the value of x

Applying the Pythagoras Theorem

$x^{2} =a^{2}+b^{2}$

substitute the values

$x^{2} =13+29.25$

$x^{2} =42.25$

$x=6.5\ units$

What two numbers multiply to get 45 but add to get -10?

goldenfox [79]

There are no two numbers that multiply to 45 but add to -10.
This is because the only numbers that multiply to get 45 are 1x45, 3x15, 5x8. None of them can add to -10 even if you make some of the numbers negative instead.

If this is a factoring problem, you may have to use the quadratic equation instead.

I ACTUALLY REALLY NEED A ANSWER FOR THIS SO IF YOU DONT ACTUALLY NO PLEASE DO NOT ANSWER!!!!

MrMuchimi

Answer:

The surface area is 10.26 feet.

Step-by-step explanation:

A=lw+l(w

2)2+h2+w(l

2)2+h2=0.8·0.8+0.8·(0.8

2)2+62+0.8·(0.8

2)2+62≈10.26131
