Answer:
-10.6 and 9/10
Step-by-step explanation:
Constants do not have any letter or variable so the ones with n or m are not constants
To find this answer you would use the formula for finding the volume of a cylinder. Because both of these cylinders are congruent, the area of the base for cylinder A I would also be the same area for cylinder B. V=pi x r^2 x h. When we substitute in what we know this is the new equation: 27 x pi = pi x r^2 x 3. Divide both sides by three and pi. This gives us 9 = r^2. Take the square roots of both sides to find the radius. The answer would be 3. Now use the formula for area of a circle to find the area of the base of cylinder B. A= pi x r^2. So the area would be 9 x pi.
Answer:
Box 2 has 3 times the volume of Box 1....
Answer:
Khalid = 140 mph
Jesse = 150 mph
Jesse has the faster train
Step-by-step explanation:
Khalid is travelling 140 mph because 280/2 is 140
Jesse is travelling at 150 mph because just like the question stated, y=150x where "x" is the total hours they traveled and 150 is the distance she traveled.
Jesse is faster because 150>140
