9514 1404 393

Answer:

  1. 113.0 cm²
  2. 2464.0 in²
  3. 95.0 ft²

Step-by-step explanation:

1. The area of a circle is given by the formula ...

  A = πr² . . . . . where r is the radius

The radius is shown as 6 cm, so the area is ...

  A = (3.14)(6 cm)² = 113.0 cm²

__

2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.

  A = (22/7)(28 in)² = 2464 in² . . . . see comment

__

3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...

  A = (3.14)(5.5 ft)² = 95.0 ft²

_____

<em>Additional comment</em>

If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.

A board is 60 centimeters long Kelly cut the board into two pieces with 14 centimeters longer than the other find the longer pie
Dahasolnce [82]

Answer:

44 cm

Step-by-step explanation:

So, it is asking what the bigger piece of the 60 cm board is. First you can divide it into two even pieces. That makes each piece 30 cm. but, it wants one of the two 14 cm bigger, right? So, now your going to add 14 cm to 30 cm, giving you 44 cm. But, if you do that then you will have to subtract 14 cm from the other board. That leaves you with the bigger board is 44 cm, and the smaller one is 16 cm.
