Answer:
2.55 cm
Step-by-step explanation: If the diameter is 5.1 cm, ten you have to divide that by 2 in order to get the radius.
5.1/2=2.55
This is a simultaneous equation
Rearrange the second to give
x - y = 1
Add the two equations
(x + y) + (x - y) = 5 + 1
2x = 6
x=3
Substitute 3 into either equation
3 - 1 = y
y = 2
Answer:
3.33333333333
Step-by-step explanation:
just alot of 3s dude
The volume of a cone with base radius and height is
Similarly, the volume of a sphere with radius is
We know that and that
So, we can set up the following equation:
We can simplify the common denominator 3, and pi appearing on both sides:
We can divide both sides by 4:
Without further information, this is all we can say: the cubed radius of the sphere is the same as 24 times the squared radius of the cone.
