Find the area of the figure. Round to the nearest hundredth when necessary.
Delvig [45]

Answer:

215.20 ft^2

Step-by-step explanation:

The figure has 2 semi-circles.

First we find the area of each circle using the formula \pi r^{2} because that is the area formula for a circle.

The semi-circle to the left gives the diameter which is 22 feet. The radius would be half the diameter thus r=11 for semi-circle one.

Then we are to find the diameter of the second semi-circle. Given the entire length to be 30 feet, 30-22 leaves us with 8 feet as its diameter thus r=4.

Left: r=11

Right: r=4

Then, plugging both into the formula for area of a circle, we get

Left: 380.1327

Right: 50.26548

We must divide each by two because we are only looking for semi-circle which is exactly half the area of a full circle.

Then,

Left: 190.066

Right: 25.1327

190.066+ 25.1327= 215.199 = 215.2ft^2

I really need help with this question!
m_a_m_a [10]

Answer:

(s-6)/r

option D

Step-by-step explanation:

The slope-intercept form a line is y=mx+b where m is the slope and b is the y-intercept.

Compare y=mx+b and y=cx+6, we see that m=c and c is the slope.

Now we are also given that (r,s) is on our line which means s=c(r)+6.

We need to solve this for c to put c in terms of r and s as desired.

s=cr+6

Subtract 6 on both sides:

s-6=cr

Divide both sides by r:

(s-6)/r=c

The slope in terms of r and s is:

(s-6)/r.

What is the volume of the cylinder below?
lbvjy [14]

\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

We need to find volume of the given Cylinder, with information :

  • radius (r) = 12 units

  • height (h) = 17 units

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = \pi r²h

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} =  \pi \sdot(12) {}^{2}  \sdot17

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} =  \pi \sdot144{}^{}  \sdot17

\qquad \sf  \dashrightarrow \:Volume_{(Cylinder)} = 2448 \pi  \:  \: unit {}^{3}

So, correct choice is B
