Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
<u>The volume and the radius are given. (V=45π, r=3)</u>
<u>1. Solve for height</u>
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
<u>2. Plug the new radius (3*3=9) into this formula and solve for "V"</u>
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π

Yes they are similar
One triangle is just smaller but they are both triangles
To get this answer all you have to do is divide 36 by 2.
Your final answer should be..

Answer:
(0.75 liters) First, divide 1.5 ÷ 2, then subtract that quotient from 1.5
Step-by-step explanation
he drinks during first match = 1.5
half of first match in the second match = 1.5 /2 = 0.75
how many more liters in the first match= first match water - second match water drinking amount
= 1.5 - 0.75
0.75 lit
