The volume of a right circular cone is calculated through the equation,

                  V = πr²h

where V is volume, r is radius of the base, and h is height. Given that height is 3 ft, this can be simplied into,
 
                V = 3πr²

The rate of change with respect to r is,
                dV/dr = 6πr

Substituting the DALE,

                dV/dr = (6)π(2 m)² = 24π

Answer: 24π.

Which is equivalent to this expression?<br> 2/150 + 3/75
Lesechka [4]

Answer:

Step-by-step explanation:

\frac{2}{150}    First reduce this to lowest term

\frac{2}{150}=\frac{1}{75}\\\\\frac{2}{150}+\frac{3}{75}=\frac{1}{75}+\frac{3}{75}\\\\=\frac{1+3}{75}=\frac{4}{75}\\

I need help please ​
qwelly [4]

Answer:

b = 55°

Step-by-step explanation:

Angles around a point will always add up to 360°

Therefore, we can write an expression where we sum the 3 angles given and equate them to 360°:

(b - 15) + 3b + (2b + 45) = 360

eliminate the brackets and collect like terms:

b + 3b + 2b - 15 + 45 = 360

Combine like terms:

6b + 30 = 360

subtract 30 from both sides:

6b = 330

divide both sides by 6:

6b ÷ 6 = 330 ÷ 6

   ⇒  b = 55

48 + 32 written as a product of two factors
masha68 [24]

Answer:

12x5 or 16x(3+2)

Step-by-step explanation:

You can factor out 16 and get 16x(3+2). Both are factors of 48+32 because 3+2 is 5 and if you do 32+48 you get 60 which can be factored by 5. Or you can add them first to get 60 and then factor out 12 to get 12x5. Hope this helps!
