Answer:

Your answer choice is correct.

Step-by-step explanation:

The length of the semicircle is ...

s = π·r = π(4 in)

The three sides of the rectangular section total ...

9 in + 8 in + 9 in = 26 in

The sum of these lengths make up the perimeter of the figure:

P = 4π in + 26 in

P = (4π +26) in

rewona [7]

Answer:

x=30

Step-by-step explanation:

to find the value of x you have to find K(constant number).

$\frac{x}{45}=\frac{18}{27}\\\frac{x}{45}=\frac{2}{3}\\ 3(x)=45*2\\3x=90\\x=\frac{90}{3}\\ x=30$

A right circular cylinder has a volume of 1 cubic meter and a height of 0.6 meters what is the radius of the cylinder to the nea

lapo4ka [179]

The volume formula of a cylinder is :

$V=\pi r^2h$

From the problem, the volume is 1 m^3 and the height is 0.6 m.

Substitute the given to the formula :

$\begin{gathered} 1=\pi r^2(0.6) \\ 1=3.14(0.6)r^2 \\ r^2=0.53 \end{gathered}$

Take the square root of both sides of the equation :

$\begin{gathered} r^2=0.53 \\ r=\sqrt[]{0.53} \\ r=0.728 \end{gathered}$

The answer is r = 0.728 m
