Answer:
Step-by-step explanation:
circumference of the circle, C=2*3.14*r
C=31.4
31.4=2*3.14*r
r=31.4/(2*3.14)=5
For this case we have that by definition, the surface area of a cylinder is given by:
Where:
r: It's the radio
h: It's the height
Substituting according to the data we have:
Thus, the surface area of the cylinder is

Answer:
x²-7 = 0 part 1 and part 2 : x = sqrt(7) or x = -sqrt(7)
Step-by-step explanation:
Solve for x:
x^2 - 7 = 0
Add 7 to both sides:
x^2 = 7
Take the square root of both sides:
Answer: x = sqrt(7) or x = -sqrt(7)
