Answer:
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
Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
= 
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
Is there a picture to this question?
Answer:
The dimensions of the rectangular box, x = y = z = 0.817 cm
Step-by-step explanation:
Given;
total surface area of the rectangular box or cuboid = 4 cm²
A rectangular box with largest volume is a cube.
The total surface area of a cube = 6 times square of one edge length.
Let the edge length = given dimensions, x, y, z
x = y = z
6x² = 4
x² = 4/6
Therefore, the dimensions of the rectangular box, x = y = z = 0.817 cm
