Answer:
125.60
Step-by-step explanation:
the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).
hope that makes sense!!
Answer:
Step-by-step explanation:
1)3.141592 either because Pi is unknown or it is non-terminating.
However, in cbse it is considered irrational so pick it
2)5/11 This is easy you should know simple division.
Hope this helps :)
Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
