Answer:

78.54 ft²

Step-by-step explanation:

Hello!

The formula for the area of a circle is A = πr², where r is the radius.

Given r is 5, find the area:

  • A = πr²
  • A = π*5²
  • A = 25π
  • A = 78.5398163397 ≈ 78.54

The area is 78.54 ft²

If an item is $99.50 how much will it be with a markup of 95%
dimulka [17.4K]
The item us going to cost 4.975
just convert the percent to decimal by moving the decimal point two spaces to the left and multiply it times the price and it will give you the discount the subtract the discount from original price and the result will be the new price.
99.50x.95=94.525
99.50- 94.55=4.975
you can round it up to 4.97

Answer:

25.3 feet per second

Step-by-step explanation:

First, let's find how much did she go down in those 3 seconds.

266-190=76

Now, let's divide 76 by 3 to find how much did she go down in 1 second

76/3=25 R1

Now, let's change 25 R1 to a Fraction.

25 remainder 1 to fraction will be 25\frac{1}{3}

Now, let's find the decimal answer

25\frac{1}{3} will be 25.33(33333)

Now, let's round our answer to the nearest tenth

25.33

so, 3 is closest to 0 not to 10

So hence, our answer is 25.3

So, the submarines elevation was changing at a rate of 25.3 feet per second

Thanks!
