Which expression can be used to find the volume of the cylinder in this composite figure?

Whitepunk [10]

Answer:

The volume of the cylinder is $112\pi\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

$V=Bh$

where

B is the area of the base

h is the height of the prism

$B=\pi r^{2}$

In this problem we have

$r=4\ cm$

$h=7\ cm$

substitute

Find the area of the base B

$B=\pi (4^{2})$

$B=16\pi\ cm^{2}$

substitute in the formula of the volume

$V=16\pi (7)$

$V=112\pi\ cm^{3}$

Express the area A of a circle as a function of its radius, r. Determine the area of a circle whose radius is 11 inches. That

nekit [7.7K]

<h2>Answer with explanation:</h2>

The function represents the area of a circle(A) is given by :-

$A(r)=2\pi r$

To determine the area of a circle whose radius is 11 inches. , we put the value of r=11 inches, we get

$A(11)=2\pi (11)$

Now, we put $\pi=\dfrac{22}{7}$ in the above function , we get

$A(11)=2(\dfrac{22}{7} )(11)\\\\\Rightarrow\ A=56.5714285714\approx56.57$

The mass of an electron is approximately 9.11 × 10 -28 grams. Find the mass of 401,000,000 electrons. 3.65311 × 10-19 grams 3.65

NNADVOKAT [17]

Answer:

$Total\ Mass = 3.65311 * 10^{-19}$ grams

Step-by-step explanation:

Given

$Mass = 9.11 * 10^{-28}g$

Required

Determine the mass of 401,000,000 electrons

To do this, we simply multiply the mass of 1 electron by the number of electrons.

This gives:

$Total\ Mass = 401,000,000 * 9.11 * 10^{-28}$

$Total\ Mass = 3653110000 * 10^{-28}$

Express 3653110000 as a standard form

$Total\ Mass = 3.65311 * 10^9 * 10^{-28}$

Apply law of indices:

$Total\ Mass = 3.65311 * 10^{9-28}$

$Total\ Mass = 3.65311 * 10^{-19}$

Hence, the mass of 401000000 electrons is $3.65311 * 10^{-19}\ grams$

Is the relationship shown by the data linear? If so, model the data with an equation.

Marina CMI [18]

Answer:

4th option

Step-by-step explanation:

The relationship is linear,

putting the value of x in the right side of the equation of option 4, you'll get the value of the left side

putting, x=1

y+4=-1/2(x-1)

y=-1/2(1-1)-4

y=-4

putting, x=7

y+4=-1/2(7-1)

y=-1/2(6)-4

y=-6/2-4

y=-3-4

y=-7
