List least to greatest
max2010maxim [7]

Answer:

C, 3 1/2, 3 19/20, 3 39/40

Step-by-step explanation:

to make this a bit easier, we can put the mixed numbers into improper fractions:

3 39/40 becomes 159/40

3 19/20 becomes 79/20

3 1/2 becomes 7/2

comparing them to each other, we see they have unlike denominators. we need to get the denominators alike so we can compare them easier

the fractions all have a common denominator of 40, so we need to multiply each fraction by a number that gives us a denominator of 40

159/40 is already fine

79/20 needs to be multiplied by 2 to get a denominator of 40

79/20 x 2 = 158/40

7/2 needs to be multiplied by 20 to get a denominator of 40

7/2 x 20 = 140/40

from least to greatest, we have the following:

140/40, 158/40, 159/40

in their original form this would be:

3 1/2, 3 19/20, 3 39/40

the answer would be C

What is the area of a circle with a diameter of 15.8 cm? Use 3.14 for pi and round your final answer to the nearest hundredth. E
wariber [46]

Answer:

A=195.97 cm^2

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We are given the diameter.  We need to find the radius

d= 2r

15.8 = 2r

Divide by 2

7.9 =r

Now we can find the area

A = pi * (7.9)^2

A = pi *62.41

Let pi = 3.14

A = (3.14) * 62.41

   = 195.9674 cm^2

We round to the nearest hundredths

A=195.97 cm^2
