## babyjay 2 years ago Can someone help with this question? A candle in the shape of a circular cone has a base of radius r and height of h that is the same length as the radius. Which expresses the ratio of the volume of the candle to its surface area (including the base) for cone v=1/3 pi r^2 and sa= pi r^2 + pi r sqrt r^2+h^2

1. sauravshakya

Volume of a cone =1/3 pi r^3 Surface Area of cone = (pi *r*l +pi r^2)

3. sauravshakya

|dw:1359031666077:dw|

4. sauravshakya

Volume/Surface AREA = {1/3 pi r^3}/{pi*r^2 +pi*r*l}

5. sauravshakya

|dw:1359031836785:dw|

6. sauravshakya

|dw:1359032554268:dw|

7. sauravshakya

I guess the last option should be r/(3+3 sqrt2)

8. babyjay

orry makes no sense to me do you mean r/3+sqrt2

Just simplify it

11. babyjay

got it think

The Radius. Which expresses the ratio of the volume of the candle to its surface area (including the base)? For a cone, V = 1/3 pi r^2 and SA = Pi r^2 √r^2 + h^2 A) 3r - √h^2 +r^2/8r - h (0 points) B) r(1 - √2) / - 3 (1 point) C) rh/3r + √h^2 + r^2 (0 points) D) r/3 + √2 (0 points) 1/1 point
