Answer:
V = 3216.9 
Step-by-step explanation:
Volume of a cylinder = π
h
We are given diameter, 16cm, and half of it is the radius
r = 8cm
h = 19cm
Substitute the values into the equation
V = π *
* 19
V = 3216.9 
Answer:
14:8 which can be simplified to 7:4 by dividing by 2.
So the ratio is 7:4. For every 7 dimes you'll have 4 quarters.
<span>4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ... + 4n( 4n + 2) = 4(4n+1)(8n+7)/6
is false because it isn't even true when n=1.
4 ⋅ 6 = 4(4*1+1)(8*1+7)/6
24 = 4(5)(15)/6
24 = 50
Also 4n(4n+2) is not even the correct formula
for the nth term. The correct nth term formula
of 4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ...
is (n+3)(n+5). So it's wrong all the way around.</span>
The answer would be 30cm squared
