a cylinder with base are 169π ft^2 and a height twice the radius. what is the lateral area and surface area of the cylinder
2 answers:
Area of base = 169 π
r = √Area = 13 ft
Given, height = 2 x 13 = 26 ft.
Lateral surface area of cylinder = 2πrh = 2 x π x 13 x 26 = 676 π ft²
Total surface area = 2πr(r + h) = 2 x π x 13 x 39 = 1014 π ft²
Thus, lateral surface area is 676 ft² and total surface area is 1014 ft²

x + (x + 3) + = 75
so you will add up all of the x 's but NOT the x^2
2x + 3 + = 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
Answer:
Rational
Step-by-step explanation:
The number comes to a stop (doesn't keep going), so it would be rational.
Centre= (-1,-2)
Radius=5
