Answer: 628
Step-by-step explanation:
2πr^2+2πrh
2(3.14)(5)^2+2(3.14)(5)(15)
2(3.14)(25)+2(3.14)(75)
2(78.5)+2(235.5)
157+471
628
So first write out the expression:

take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
Answer:
x < 3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Our objective is to isolate n one side of the equation. The steps are as follows...
a=m-n
(Add n to both sides)
a+n=m-n+n
(The -n and +n cancel out, on the right side of the equation)
a+n=m
(Now subtract a from both sides)
a+n-a=m+a
(The +a and -a cancel out, on the right side of the equation)
n=m+a
Answer:
0.7 Ls
Step-by-step explanation:
A liter (L) and a milliliter (mL) are two units for measuring capacity in the metric system. The bottle pictured at the right holds 1 L of water. About twenty drops of water equals 1 mL. To convert liters to milliliters, To convert milliliters to liters, multiply by 1,000.
