Answer:

a=95.0 in^2

Step-by-step explanation:

The area of a circle is:

a= $\pi$ r^2

First, we must find the radius

r=d/2

r=11/2

r=5.5

Substitute 5.5 in for r in the formula

a= $\pi$ 5.5^2

a= $\pi$ 30.25

Substitute 3.14 in for pi

a=3.14*30.25

a=94.985

Rounded to the nearest tenth:

a=95.0 in^2

Hope this helps! :)

Romashka [77]

Answer:

Mean = 90, Median = 93, Mode = 90, Range = 6

Step-by-step explanation:

Mean:

96 + 90 + 94 + 93 + 90 = 463

463 ÷ 5 = 92.5

92.5 to nearest tenth = 90

Mean = 90

Median:

90, 90, 93, 94 ,96

Median = 93

Mode

96, 90, 94, 93, 90

Mode = 90
