Answer:

37.699 cm³

Step-by-step explanation:

Sa of cone:

pi×r×l + pi×r²

(3pi × l) + (pi × 3²) = 24pi

3l + 9 = 24

3l = 15

l = 5 (slant height)

Height: h

h² + r² = l²

h² + 3² = 5²

h² = 16

h = 4 cm

Volume = ⅓ × pi × r² × h

= ⅓ × pi × 3² × 4

= 12pi cm³

= 37.69911184 cm³

Answer:

7 inches

Step-by-step explanation:

First you have to find the average height of each class.

4th Grade:

56, 47, 54, 51, 53, 58, 48, 54, 46, 53

Then you have add it all up and divide it by how many students there are.

56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520

520 ➗10= 52

Same process for the 7th Grade.

You end up getting 52 and 59. You then Subtract it to get the answer to the question.

52 - 59= 7 inches
