Let's solve for "r" by bringing them all to one side.
-3r=6-4r
+4r    +4r
r=6
So, r is equal to 6.

So you have to add the like terms together,

6 - 4r = -3r
    +4r   +4r

        6=1r
   Divide 1 to both sides.
       
      6=r

Find the surface area of a right cone with diameter 30 in. and slant height 8 in.Your answerEXTRA CREDIT: Find the surface area
Anon25 [30]

<u>Answer:</u>

Surface area = 1084 in²

<u>Step-by-step explanation:</u>

To find the surface area of a right cone, we can use the following formula:

\boxed{{Area = \pi r^2 + \pi rl}},

where:

• r = radius

• l = slant height.

In the question, we are told that the diameter of the cone is 30 in. Therefore its radius is (30 ÷ 2 = ) 15 in. We are also told that its height is 8 in.

Using this information and the formula above, we can calculate the surface area of the cone:

Surface area = \pi \times (15)^2 + \pi \times 15 \times 8

                     = 345 \pi

                     \approx 1084 in²
