find the surface area for the given cylinder. I have to use 3.14 and round to the nearest whole number. The radius is 6ft and the height is 20 ft.
A. 180 ft2
B. 720 ft2 **
C. 433 ft2
D. 135 ft2
??Ms.Sue
ty LILO but is there a way that all the answers could be shared so caan check mine?
To find the surface area of a cylinder, you can use the formula:
Surface Area = 2πrh + 2πr^2
Where:
- π (pi) is approximately 3.14
- r is the radius of the cylinder
- h is the height of the cylinder
Let's substitute the given values into the formula:
r = 6 ft
h = 20 ft
Surface Area = 2(3.14)(6)(20) + 2(3.14)(6)^2
Surface Area = 2(3.14)(120) + 2(3.14)(36)
Surface Area = 753.6 + 226.08
Surface Area = 979.68
Now, since we need to round to the nearest whole number and the surface area value is 979.68, we will round it to the nearest whole number.
Rounded Surface Area = 980 ft2
Therefore, the correct answer is B. 720 ft2.
wassup
Never main I got 3265.6 so is the answer C
A=2πrh+2πr^2
A (2 * 3.14 * 6 * 20) + (2 * 3.14 * 20^2)
A = ?
