A cone has volume V, radius r, and a height of 12 cm.
Another cone has the same height and 1/3 times the
radius of the original cone. Write an expression for its
volume.

Answers

Answer 1

Answer:

I think it is 4/9 pi r

Step-by-step explanation:

according to the condition given:

2nd cone has:

Height = 12cm

r= 1/3r (cause it's given 1/3 of radius of the original cone)

We know that volume of a cone is = 1/3 pi (r)^2 h

Now substitute the values:

1/3 * pi* (1/3r)^2 * 12

when u simplify u will get

pi* 1/9*r*4 = 4/9 pi r

So, the answer is probably 4/9 pi r.

What is the zero of
q(x) = -7/3x + 14?

Answers

Answer:

x = 6

Step-by-step explanation:

Solve for x:

-(7 x)/3 + 14 = 0

Put each term in -(7 x)/3 + 14 over the common denominator 3: -(7 x)/3 + 14 = -(7 x)/3 + 42/3:

(-(7 x)/3 + 42/3) = 0

-(7 x)/3 + 42/3 = (-7 x + 42)/3:

((-7 x + 42)/3) = 0

Multiply both sides of (-7 x + 42)/3 = 0 by 3:

(3 (-7 x + 42))/3 = 3×0

(3 (-7 x + 42))/3 = 3/3×(-7 x + 42) = -7 x + 42:

(-7 x + 42) = 3×0

0×3 = 0:

-7 x + 42 = 0

Subtract 42 from both sides:

(42 - 42) - 7 x = -42

42 - 42 = 0:

-7 x = -42

Divide both sides of -7 x = -42 by -7:

(-7 x)/(-7) = (-42)/(-7)

(-7)/(-7) = 1:

x = (-42)/(-7)

The gcd of 42 and -7 is 7, so (-42)/(-7) = (-(7×6))/(7 (-1)) = 7/7×(-6)/(-1) = (-6)/(-1):

x = (-6)/(-1)

(-6)/(-1) = (-1)/(-1)×6 = 6:
