12=4.7k+11.5 how do you do this step by step? answer for k

k=0.106383

Step-by-step explanation:

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

12=4.7k+11.5

Step 1: Flip the equation.

4.7k+11.5=12

Step 2: Subtract 11.5 from both sides.

4.7k+11.5−11.5=12−11.5

4.7k=0.5

Step 3: Divide both sides by 4.7.

4.7k

4.7

=

0.5

4.7

k=0.106383

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
