Answer:
Step-by-step explanation:
From the way the answers are presented, it can be seen that x refers to the radius of the base of the cone
radius: 
and we are told that the height is twice the radius, so:
height: 
and now we use the formula to calculate the volume of a cone:
where 
is volume, 
is radius, and 
is the height. and 
is a constant
in this case
so we substitute thisvalues in the formula for the volume:
Rearranging the terms
which is option A.
Numbers that are 510 to 540 (with zeroes) I'm not too sure about the ones place but also numbers 1-4. For example, 521, 1 rounded to 20 = 20. 20 rounded to 500 = 500. You get me?
Answer:
Step-by-step explanation:
=> 8x-6 = 15
Adding 6 to both sides
=> 8x = 15+6
=> 8x = 21
Dividing both sides by 8
=> x = 21/8 (In its simplest form)
