Why is the formula for curved surface area of a cone πrl? I just don't get how that makes sense, why not dlπ, so you find the ci

rcumference, and then times that by the length? Doesn't that only give us half the curved surface area?

I don't get this... someone explain this plum thing please...... Before a plum is dried to become a prune, it is 92% water. A pr
taurus [48]

Answer:

21.74 But if it tells you to round I would round to 21 lbs

Step-by-step explanation:

its basically just a ratio of 92 to 20

92/20=4.6

92-20=72% the amount that is lost

so given that the plum is 100 lbs we know that 72% is depleted

(72/92 = .78)X100= 78 lbs depleted

Lastly 100-78 =22 for the remaining weight of the prunes.

similarly , breath and height will be also multiple of 3

so, V1 = 60

then V2 = 60 *3*3*3 = 1620 cubic cm

hope it helped
