Answer:

The area of the circle is 314mm²

Step-by-step explanation:

To solve this problem we have to use the formula for calculating the area of a circle

a = area

π = 3.14

r = radius

d = diameter

r = d/2

r = 20mm / 2

r = 10mm

a = π * r²

we replace the known values

a = 3.14 * (10mm)²

a = 3.14 * 100mm²

a = 314mm²

The area of the circle is 314mm²

Bill booked a ride to the airport. If it rains, the traffic will be bad and the probability that he will miss his flight is 0.06

kvasek [131]

Answer:0.614

Step-by-step explanation:

Given

Probability he will miss flight if it rains=0.06

Probability he will miss flight it does not rain=0.01

Given the probability of rain=0.21

Therefore Probability that it will not rain=1-0.21=0.79

Probability that he will miss the flight $=0.21\times 0.06+0.79\times 0.01=0.0205$

P(actual raining and he missed the flight| he miss the flight) $=\frac{0.21\times 0.06}{0.21\times 0.06+0.79\times 0.01}$

$=\frac{0.0126}{0.0205}=0.614$
