What is the exact volume of the cone with a radius of 7in and a height of 4in use 3.14 for π

vfiekz [6]

Answer:

The exact volume of the cone is $\frac{196}{3}\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=7\ in$

$h=4\ in$

substitute the values

$V=\frac{1}{3}\pi (7^{2})(4)=\frac{196}{3}\pi\ in^{3}$

What’s the measure of the angle theta?

11111nata11111 [884]

Answer:

∅ = 50°

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

You need to use Law of Sines

$\frac{a}{sinA} =\frac{b}{sinB} = \frac{c}{sinC}$

Here you will be doing $\frac{a}{sinA} =\frac{c}{sinC}$

a and c are the lengths, while A and C are the angles

$\frac{3.46}{sinA} = \frac{2.54}{sin43}$ you want to get the denominators out from underneath so multiply both sides by sinA and sin43

$3.46sin43 = 2.54sinA$

Now you want to get sinA alone so divide both sides by 2.54

$\frac{3.46sin43}{2.54} = sinA$ now get A alone

$sin^{-1} (\frac{3.46sin43}{2.54}) = A$ put that into the calculator

$49.61741033 = A$

9(9h + 4b + 9), for h = 7 and b = 3<br><br> Evaluate

irakobra [83]

So, when adding in the 7 and 3 the new equation is:
9{(9x7)+(4x3)+9}

Following pemdas, you have to do parenthesis first. So now the equation is:
9(63+12+9)

Now distribute the 9:

567 + 108 + 81

And finally solve as a normal addition problem:

567 + 108 + 81= 756

So, the answer is 756.

I hope this helps:)
