## anonymous one year ago 8.) The lateral area of a cone is 612 pi cm^2. The radius is 43 cm. What is the slant height to the nearest tenth of a centimeter? My answer: 9.1 cm. Is that correct? 9.) What is the lateral area and the surface area of the cone shown below? Round the answer to the nearest tenth. The figure is not drawn to scale.

my answer: LA= 1,187.5 ft^2, SA= 1,803.3ft ^2. Is that correct?

lateral area $\Large LA = \pi*r*s$ r = radius s = slant height

mhm

9. jim_thompson5910

so LA = pi*r*s 612*pi = pi*43*s solve for s

I am guessing that I didn't do 8. correctly?

11. jim_thompson5910

yes, #8 is incorrect

12. anonymous

darn. Is it 14.2?

13. jim_thompson5910

yes

14. anonymous

okay. Thanks you for correcting me

15. jim_thompson5910

I agree with what you got for #9
