Answer:
The radius of the water bottle is 2.72cm
Step-by-step explanation:
In this question, we are concerned with calculating what the radius of the cylindrical water bottle is given its volume and height.
Mathematically, the volume of a cylinder is V = pi * r^2 * h
From the question, we know that V = 179 cm^3. , h = 7.7cm while r = ?
we substitute these values into the volume equation.
179 = pi * r^2 * 7.7
179 = 3.14 * r^2 * 7.7
179 = 24.178 * r^2
r^2 = 179/24.178
r^2 = 7.403
r = square root 7.403
r = 2.72 cm
Draw 2 circles one cut straight down the middle and straight across the middle from the side making a plus shape then do the same to the 2nd but also in each of the 4 triangles you made in the 2nd one split them down the middle again
Greetings!
"<span>The circumference of a circle is 12 inches. What is the radius?"...
We can use the formula to find the circumference of circle to solve this:
