Answer:
TRUE
Step-by-step explanation:
Lateral area of cone is given by: πrl
where r is the radius and l is the slant height
Here r=r and l=2h
Hence, lateral area of cone A= π×r×2h
= 2πrh
Lateral area of cylinder is given by: 2πrh
where r is the radius and h is the height
Lateral area of cylinder B=2πrh
Clearly, both the lateral areas are equal
Hence, the statement that:The lateral surface area of cone A is equal to the lateral surface area of cylinder B. is:
True
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8
The sum of all 3 angles is 180 degrees, you should be able to solve from here.
Answer:
second and third choice
Step-by-step explanation:
supplamentary = add up to be 180
I do believe it is answer c, but not 100% on that due to the fact that when i worked it i got c, but when i googled alot got other answers. sorry i know thats not much help
