Answer:
2nd one
Step-by-step explanation:
Oi :)
a= l*w
a=1.5 * 0.75
a= 1.125
The correct answer is C. So, lets go first to the equations that determine the volume of these solids. For the cylinder, that is simple; pi*r*r*h where r is the radius, h is the height and pi is the constant 3.14. For the cone, it is not easy to derive but one gets that the formula is:
.
We notice thus that
. That holds irrespective of their radius or height; we only need to know that the heights and radii of the two objects are the same. Now, we have thus that:
.
We can check if this holds for Jared's statement; 1178/4712=0.25=1/4. So, it does not hold and thus Jared's statement is incorrect.
Answer:
d=7/2
Step-by-step explanation:
3/4d-1/2=3/8+1/2d
multiply all by 8, to make them into whole numbers (makes it easier)
6d-4=3+4d
move terms
6-d-4d=2d
3+4=7
7=2d
d=7/2
