Answer:
Radius = 4.95 cm
Step-by-step explanation:
I am assuming you need the radius of the base of the cylinder.
Volume = 1.54 * 1000 = 1540 cm^3
Volume = πr^2h so:
1540 = π*r^2*20
r^2 = 1540/20 π = 24.510
r = 4.95 cm.

Answer:</h3>
It would be 21b² -32b -5
<h3>
Step-by-step explanation:</h3>
By using the FOIL method, you can simplify the equation.
<em>The Foil Method is </em><u><em>ac + ad + bc +bd</em></u><em>, or </em><u><em>First, Outer, Inner, Last.</em></u>
First, you multiply the first term in each bracket.
3b * 7b = 21b²
Next, you multiply the outer term in each bracket.
3b * 1 = 3b
Then, you multiply the inner term in each bracket.
-5 * 7b = -35b
After that, you multiply the last term in each bracket.
-5 * 1 = -5
Lastly, you combine like terms.
21b² + 3b -35b -5 ---> 21b² -32b -5
<em>21b² -32b -5 would be your answer, since you cannot simplify the equation anymore.</em>
-12+5
for -12.34,we take it as -12
for -4.8,we take it as -5
to measure the difference,here's what you need to do
-12-(-5)
=-12+5
thus the ans is -12+5
