Find the missing measure for a right circular cone given the following information. find l. a. if r = 6 and h = 8

Lateral area = 188.4 square units

Step-by-step explanation:

We have to find the lateral area of a cone whose radius(r) and height(h) is given

  r= 6 and h=8

Now, we have to find the slant height 'l' of the cone

l²=r²+h²

l²=6²+8²

l²=100

⇒ l=10

Hence, lateral area= πrl

                               = 60π

                              =  188.4 square units

3; 9 is 8 to -4
