A drumstick ice cream cone is 4 inches in diameter and has a height of 7 inches and filled with ice cream. The cone also has a sphere of ice cream that's 5 inches in diameter on top. What is the total amount of ice cream? Round to the nearest tenth.

48.7 cube inches

Step-by-step explanation:

Let us assume that the ice cream filled the entire volume of the cone.

Diameter of cone = 4 inches

height of cone = 7 inches

diameter of a sphere of ice cream = 5 inches

Total amount of ice cream = volume of cone + volume of sphere

volume of cone = h

r =

  = = 2 inches

volume of the cone = x x x 7

                           = x x 4 x 7

                           = 29.3333 cube inches

volume of sphere =

r =

  = = 2.5 inches

volume of sphere ice cream = x x

                                   =   x x

                                   = 19.40 cube inches

So that,

Total amount of ice cream = 29.33 + 19.40

                                   = 48.7 cube inches

its d. the first coordintaes are 10,32

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
