Mathematics
1 answer:
dlinn [17]3 years ago
7 0

Answer:

  x = 5

Step-by-step explanation:

Corresponding sides are proportional, so we can write the proportion ...

  (x -2)/x = (x +1)/(x +5)

  (x -2)(x +5) = x(x +1) . . . . . . . multiply by x(x+5)

  x^2+3x -10 = x^2 +x . . . . . eliminate parentheses

  2x = 10 . . . . . . . . . . . . . . subtract x^2+x-10

  x = 5 . . . . . . . . . . . . . . divide by 2

Answer :

V = ⅓πr²h

= ⅓ × 3.14 × 36 × 8

= 3.14 × 12 × 8

= 301.44 units²

= <u>3</u><u>0</u><u>0</u><u> </u><u>units²</u> (rounded)

So, the volume of the cone is 300 units²
