Answer: $\bold{C)\ -\dfrac{1}{2}}$

Step-by-step explanation:

$.\qquad \dfrac{x+2}{15}=\dfrac{x+1}{5}\\\\\\\rightarrow (15)\dfrac{x+2}{15}=\dfrac{x+1}{5}(15)\\\\\\\rightarrow x+2=3(x+1)\\\\\rightarrow x+2=3x+3\\\\\rightarrow \qquad 2=2x+3\\\\\rightarrow \qquad -1=2x\\\\\rightarrow \qquad -\dfrac{1}{2}=x$

Calculate the volume of each geometric shape:

pav-90 [236]

Answer:

a) 235.62in³

b) 904.78in³

Step-by-step explanation:

a) The formula to find the volume of a cylinder is:

$V = \pi r^2h$

We are given that r = 5 and h = 3, so we can just plug in and solve:

$V = \pi(5)^2(3) = 235.62in^3$

b) The formula to find the volume of a sphere is:

$V = \frac{4}{3}\pi r^3$

We are given that the diameter is 12in, which means that the radius (r) must be 6in (half the diameter). Now, we can plug in and solve:

$V = \frac{4}{3}\pi (6)^3 = 904.78in^3$
