By the larger circle, they mean the red area plus the white area. We now must calculate the area of both.

Small circle area (white area)= PI * 4.02^2 = 50.77 square inches

TOTAL Circle Area (red and white) = PI * 8.01 *8.01 = 201.56

(Red area)= PI * 8.01^2 -50.77

(Red area)= 201.56 -50.77 = 150.79

A point chosen in the TOTAL 201.5648988136 square inch area has the probability of being in the read area=

red area / TOTAL area = 150.79 / 201.56

probability = .748 = 74.8% of the time.

miss Akunina [59]

Answer:

The  calculation of Mrs. Hernanadez will affect by 1.375 inches lesser.

Step-by-step explanation:

Given:

Length of the Kitchen shelf = 26 3/8 inches

But she measured as 25 inches

So the error in the measurement will be

=>Correct length of the shelf - Incorrect length of the shelf

=> 26\frac{3}{8} - 25

Coverting the mixed fraction to fraction,

=> \frac{211}{8} - 25

=> 26.375 - 25

=>1.375
