Answer:
75.39 in^2 (round to the nearest hundreds)
Step-by-step explanation:
I think that we have to find the lateral area
circumference = 2 x radius x pi = 2 x 4 x pi = 25,13 in^2 (round to the nearest hundreds)
lateral surface = (circumference x slant height)/2 = (25,13 x 6)/2 = 75,39 in^2 (round to the nearest hundreds)
Answer:
3/7 and 4/17
Step-by-step explanation:
a) given that Shen is playing a game and the probability of unlocking the treasure test is 3/10.
To find the odds in favour of his character unlocking the treasure chest.
Since probability = 3/10 we have favourable and total are in the ratio 3:10
i.e. favourable:Favourable+unfavourable= 3:3+7
Hene odds= favourable:unfavourable =3/7
Answer is 3/7
b) Given that odds against choosing a blue block are 13/4
This means there are 4 blue blocks and 13 other colour blocks.
Total blocks= 13+4 =17
No of blue blocks = 4
Probability of selecting blue block=4/17
Answer: 20
Step-by-step explanation:
The base square is 4 x 4, which is 16. That part is easy, but the other part needs more thinking.
We have two more visible full squares, which we can add on to our 16, putting it at 18. But that half squares, we have 4 total have squares. We know that 1/2 + 1/2 = 1
So, 1/2 + 1/2 + 1/2 + 1/2 = 2.
We eventually get 16 (original square) + 2 (two other full squares) + 2 (half squares) resutling in 20.
I have to have 20 characters but x is 22
