Answer:
506.7 cm²
Step-by-step explanation:
The amount of cardboard needed would be the surface area of the cone,
S= pi(r)(l+r) where r is the radius and l is the slant height.
You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.
Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²
Let me know if you have any questions about my steps!
Xiao should have written this
Xiao's mistake was that
he forgot to put 3 times 30 so it
could be 90.
3(20) + 3(30)
60 + 90
150

Given :There are 13,245 eligible voters in one town. In a poll of 812 eligible voters from this town, 388 say that they plan to vote in the next mayoral election.
To Find : Based on this sample statistic, estimate the number of eligible voters in this town who will not vote in the next mayoral election.
Solution.:
Let x be the no. of eligible voters out of 13245 in this town who will vote in the next mayoral election.
We are given that In a poll of 812 eligible voters from this town, 388 say that they plan to vote in the next mayoral election.
So, ATQ
So, the no. of eligible voters out of 13245 in this town who will vote in the next mayoral election. is approximately 6328
So, the number of eligible voters in this town who will not vote in the next mayoral election = 13245- 6328 = 6917
Hence the number of eligible voters in this town who will not vote in the next mayoral election is 6917
