calculate the lateral area and volume of a truncated cone of radii 10cm and 12cm and a slant height of 15cm​

The lateral surface is 212

Step-by-step explanation:

Lateeal surface area is = Ph

12+12+10+10(15)=212

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
