Find the area of a circle with diameter 31.6 cm, both in terms of p and to the nearest tenth. Use 3.14 for p. Your
A = 249.64p cm2» 783.9 cm2
A = 63.2p cm2» 198.4 cm2
A = 31.6p cm2» 99.2 cm2
A = 998.56p cm2» 3135.5 cm2

Option (1)

Step-by-step explanation:

Formula to get the area of a circle is given by,

Area = πr²

Here r = radius of the circle

Since, Radius of a circle =

Therefore, Radius of the circle with diameter = 31.6 cm will be,

Radius =

            = 15.8 cm

Now Area of the circle = π(15.8)²

                                      = 249.64π cm²

                                      = 783.87 cm²

                                      ≈ 783.9 cm²

Therefore, Option (1) will be the correct option.

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 %
