There are 238 juniors at a high school. the ratio of girls to boys in the junior class 3: 4. how many juniors are girls? how many are boys?

Well, for ratio problems like this, here’s what you do:

1. Add the numbers in the ratio together:

3 + 4 = 7

2. Divide that number by the quantity given:

238 / 7 =
34

3. Multiply each part of the ratio by the quotient:

4 x 34 = 136

3 x 34 = 102

102 + 136 = 238
4. Answer the problem using the information you just found:

The ratio of girls to boys in the junior class is 102 : 136.

Option (1)

Step-by-step explanation:

Volume of a cylinder is given by the formula,

V = πr²h

Here, V = Volume

r = Radius of the circular base

h = Height of the cylinder

From the picture attached,

r = 8 in.

h = 0.5 in.

By substituting these values in the formula,

V = π(8)²(0.5)

  = 32π

  = 32(3.14)

  = 100.48 in³

Therefore, Option (1) will be the correct option.
