the formula to find the surface area of a sphere is to take the radius of the sphere and square
it and multiply that amount by pi and then multiply that by 4. this is written algebraically as
s=4πr
2
, where s is the surface area, r is the radius, and the value of π is 3.14. rewrite the
equation to solve for the radius of the sphere if you know the sphere’s surface area. then
estimate the radius of a sphere given a surface area of 500 meters2
.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

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 %
