The volume of a cone-shaped hole is 16 pi ft cubed . If the hole is 3 ft deep, what is the radius of the hole?

VashaNatasha [74]

V = 1/3 • π • radius cubed • height

If the volume is is 16π and the height is 3, then 16π = 1/3 • π • r cubed • 3

16π ÷ (1/3 • π • 3) = 16

radius squared = 16 √16 = 4, so radius = 4

You can also check: 1/3 • r cubed • 3 = 16 The only value left to multiply is π

X Find the value of x. Show 3 10 your work.

pickupchik [31]

Step-by-step explanation:

Hello, there!!!

Let ABC be a Right angled triangle, 

where, AB = 3

BC= 10

and AC= x

now,

As the triangle is a Right angled triangle, taking angle C asrefrence angle. we get,

 h= AC = x

p= AB = 3

b= BC= 10

now, by Pythagoras relation we get, 

 $h = \sqrt{ {p}^{2} + {b}^{2} }$ 

 $or ,\: h = \sqrt{ {3}^{2} + {10}^{2} }$ 

by simplifying it we get, 

h = 10.44030

Therefore, the answer is x= 10.

Hope it helps...

What is the polar form of -4+5i?

kifflom [539]

z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- $tan^{-1} (\frac{5}{4} )$

Step-by-step explanation:

Given,

-4+5i is a complex number.

To find the polar form.

Formula

z=x+iy

r² = mod of (x²+y²)

θ = $tan^{-1} (\frac{y}{x} )$

So, the polar form will be z=r(cosθ+i sinθ)

Now,

r² =(-4)²+5² = 41

or, r = √41

θ =π- $tan^{-1} (\frac{5}{4} )$ [ since the point is in second quadrant]

Hence,

z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- $tan^{-1} (\frac{5}{4} )$
