Formula
V = (1/3) pi * r^2 h
pi = 3.14
d = 3 cm. (very small)
r = d/2 = 3/2 = 1.5 cm
h = 7 cm
V= (1/3) 3.14 * 1.5^2 * 7
V = 1.04 * 1.5^2 * 7
V = 16.485 cm^3
L <<<<==== answer.
The answer would be 1.52777777777778, rounded to the nearest tenth would be x=1.5
I'm going to assume that you're asking for the<em> equation</em> of that circle.
It's
<u>(x + 4)² + (y - 3)² = 16</u>
Answer: Marcy will need to route 10 calls to spend a total of 20 mintes on the phone.
Step-by-step explanation: 1 call = 2 minutes.
(2x+11) = ( 5x-19)
subtract 2x from each side. So 2x - 2x =0 and 5x - 2x = 3x.
Now your equation is 11 = 3x- 19.
Next, add 19 to each side. - 19 + 19 = 0 and 11 + 19 = 30.
Your equation is now 30 = 3x.
Now divide by 3x on each side. 3x / 3x= x and 30 / 3 = 10.
<em>So your answer would be x = 10</em>.
