Will Give Brainliest if Correct! Which of the following formulas would you use in order to find the surface area of the solid figure below?

SA = r + r 2
SA = 4 r 2
SA =2 l + l 2
SA = 2 rh + 2 r 2

first option is right, r+r2

a.) SA = r + r 2

Step-by-step explanation:

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 %

answer: 72: 111
