Hello!
To find the surface area of a cylinder you use the equation
SA is surface area
r is radius
h is height
PUt in the values you know
Square the number
Multiply 7 and 18
Multiply 126 by 2
Multiply the 49 by 2
Add
The answer is
Hope this helps!
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
Answer:
c
Step-by-step explanation:
this would look like this: 0.0000001^10
If we were to do 0.0000001*0.0000001 it would be 0.00000000000010
We doubled the zeroes and moved the one up. Continue on until you reach the tenth power.
