A cone with a radius of 9 cm has the same surface area as a cylinder with a radius of 6 cm and a height of 18 cm. What is the height of the cone to the nearest tenth?

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
