By knowing the circumference of the base of the cone, we see that the radius is 4 centimeters.

<h3>How to find the radius of the cone?</h3>

Notice that in the first figure, the length of the arc AB is L = 8π cm.

Then, that arc will be the bottom part of the cone. Then we can see that the circumference of the base of the cone will be equal to the length of the arc.

And remember that for a circle of radius R (like the base of the cone), the circumference is:

C = 2πR.

Then we will get:

8π cm = C = 2πR

( 8π cm)/ 2π = R

4cm = R

The radius of the cone is 4cm.

The system x−6y=4, 3x−18y=4 has no solution.

stealth61 [152]

Ok fist you wanna change your question into a equation so it would turn into x-6 y=4 and 4.3x - 18 y = 4 then multiple both sides and that pups give you 43x - 180 y = 40 and eliminate one variable and I don’t wanna keep explaining but the the answer is

adell [148]

Answer:

0.60 gal to 0.12 gal can be rewritten as:

$\frac{0.60}{0.12} =\frac{0.6}{0.6(0.2)} =\frac{1}{0.2}$

$\frac{1}{0.2}*1=\frac{1}{0.2}*\frac{10}{10} =\frac{10}{2} =5$
