The rectangular prism shown has a length of 10 cm, a width of 10 cm, and a height of 6 cm. Find the length of the inner diagonal
melamori03 [73]
<h3>Answer:</h3>

15.36 cm

<h3>Explanation:</h3>

The Pythagorean theorem tells you ...

... AC² = AB² + BC² . . . . . relation for face diagonal

... AD² = AC² + CD² . . . . . relation for space diagonal

Subsituting the expression for AC² given by the first equation, the second equaiton becomes ...

... AD² = AB² + BC² + CD²

... AD² = (100 cm²) + (100 cm²) + (36 cm²) = 236 cm²

Taking the square root, we have ...

... AD = √236 cm = 2√59 cm

... AD ≈ 15.36 cm

IceJOKER [234]

Answer:

1+cos^2(2A)=(1−cos2(2A))+2cos^2(2A)

=sin^2(2A)+2(cos^2A−sin^2A)^2

=(2sinAcosA)^2+2(cos^4A−2cos^2Asin^2A+sin^4A)

=2(cos^4A+sin^4A)

Anit [1.1K]
Cylinder height = volume / PI * radius^2
cylinder height =1,205.76 / PI * 8^2
cylinder height = <span> <span> <span> 5.9969582557 </span> </span> </span>
which I guess can be safely rounded to 6 inches
