For angle a it will be 42degrees and for angle b it will be 138degrees and i am 100%sure
4*2=8. 8/2.5=3.2. The height is 3.2 meters.
Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
To Find?
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
Substituting values in the formula:
- Hence, (B) 399.4 cm² is right answer.
6. 64 hours so about 7 hours if you need to round up
hope this helps
please thank me
since LM=LN there values are same which is given as 5.5 cm and MN =7cm
now draw a line LM which is 5.5 cm long. From one point of this line construct an arc 5.5 cm in upward direction.Then from the opposite end of the same line LM construct an arc 7 cm long in upward direction. Let it meet the the first arc at any point. The arcs will meet for sure at any angle. Join the two ends of line LN to this point where they meet. We get a triangle!
Remember to mark LM , LN and MN as soon as u draw them so as to avoid confusion.
