1/3*3.14= 1.046666666 ect.
Answer:
Its option C
Step-by-step explanation:
to find the volume you multiply the length, width and height together.
you do not give a value for PI so I am using 3.14
V=PI x r^2 x H
you know volume and radius so put those into the equation
525 = PI (3.14) x 5^2 x H
525 = 3.14 x 25 x H
525 = 78.5 x H
divide both sides by 78.5
6.687 = H
round off answer as needed 6.7cm or 6.69cm
NOTE : the answer may vary slightly depending on the value of PI used.
but this is how you calculate the height.
The Pythagorean Theorem states that for right triangles:
a^2=b^2+c^2
a= the hypotenuse
b and c equals the other two sides.
In this case we are given the hypotenuse so we can rearrange the equation to look like this b^2=a^2-c^2 (I subtracted c^2 from both sides). I know a and c so I can solve for b.
We get rid of a square by implementing a square root on both sides and get:
b=sqrt(a^2-c^2) .... b=sqrt( (sqrt(34))^2 - 3^2)
b= sqrt(25) ..... b=5
