PLEASE HELP HURYUUU

A. P = 29.7 m

Step-by-step explanation:

6² + 8² = y²

36 + 64 = y²

y² = 100

√y² = √100

y = 10

10 ÷ 2 = 5

5 × 3.14 × 2

31.4

31.4 ÷ 2 = 15.7

15.7 + 6 + 8 = 29.7

i think the answer is b

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
