Answer:

The radius of the cylinder is r=3\ ft

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

V=\pi r^{2} h

we have

V=169.65\ ft^{3}

h=2r\ ft

assume

\pi=3.14

substitute the values and solve for r

169.65=(3.14)r^{2} (2r)

169.65=(6.28)r^{3}

r^{3}=169.65/(6.28)

r=3\ ft

How does the position of the decimal point in a quotient as you divide by increasing powers of 10
Digiron [165]
The value decimal point is changing going to the right as you divide a number by 10. For example => 2000.3 / 10 notice the decimal point => 200.013, the value of decimal numbers increases as the value of whole number decreases.Let’s divide again => 200.013 / 10 => 20.0013 , now we already have 4 digits in our decimals. So, simply as we divide the given number by 10, the decimal point moves to the left making the value of whole number decreases and making the number of digits of decimal increase.
