Using the formula for area of a circle:

Area = pi x radius^2

Replace area with the given value:

39.62 = pi x radius^2

Divide both sides by pi

Radius^2 = 39.62/pi

Radius^2 = 12.62

Solve for radius by taking the square root of both sides

Radius = sqrt(12.62)

Radius = 3.55 cm

If you were to round off the measurement 2.33501 grams to three digits, you would get
Minchanka [31]

Answer:

  2.34 grams

Step-by-step explanation:

The first 3 digits of the number are 2, 3, 3. The next digit is 5, which is more than 4, so 1 is added to the digit to its left and all digits to the right of the first three are dropped.

2.33 becomes 2.34 because of the 5 in the thousandths place.

Your rounded measurement is 2.34 grams.

a picture contains 40 fluid ounces of iced tea Shelby pours 3 cups of iced tea how many pints of ice we are left in the picture
Sladkaya [172]
We want to convert the 3 cups into ounces so we can work with it. 3 cup x 8 ounces per cup = 24 ounces. Now we want to subtract 24 from 40. 40-24= 16. We now want to convert pint into ounces. 1 pint= 2 cups= 16 ounces per pint. 16 ounces of iced tea/16 ounces in a pint equals 1 full pint.

You want to buy some beans . A 6 - ounce package costs $2.16 . A 15 - ounce package costs $5.92 . A 20 - ounce package costs $7.
seraphim [82]

Step-by-step explanation:

Given that,

A 6 ounce package costs $2.16

A 15 ounce package costs $5.92

A 20 ounce package costs $7.60

So,

Cost of 1 ounce of package = 2.16/6 = $0.36

Cost of 1 ounce of package = 5.92/15 = $0.394

Cost of 1 ounce of package = 7.6/20 = $0.38

Hence, 'a 6 ounce package costs $2.16' is the best deal to buy.
