Please help! I’m very confused on this question. I’m not very good at geometry.
Ahat [919]

Well, to find the perimeter we have to add all of the side lengths, so let's do that:

2x+3 +2x+3 +2x

And we know that this equals 36 so let's solve for x

2x+3+2x+3+2x = 36

6x+6 = 36

6x = 30

x = 5

So we know know that x = 5.

Now all you have to do is plug in the values of x into the lengths

2(5) + 3

= 10+3

= 13 is the length of two of the sides.

2x

= 2(5)

= 10

And 10 is the length of the last side.

Answer:

4.8

Step-by-step explanation:

V_{sphere} = \frac{4}{3} \pi r^3

r^3 = \frac {3 \times 144\pi}{4\pi}

r^3 = 3 \times 36

r^3 = 108

r =  \sqrt[3]{108}  \\  \\ r = 4.7622031559 \\  \\ r \approx \: 4.8 \:
