<u>Answer:</u>

19.15

<u>Step-by-step explanation:</u>

16.80 x 5% = 0.84

16.80 - 0.84 = 15.96

15.96 x 20% = 3.19

15.96 + 3.19 = 19.15

The formula for the area of a circle is A = πr2, where A = area and r = radius.
BaLLatris [955]

The area of a circle with radius of 5 feet is 25π square feet

Step-by-step explanation:

The area of a circle is found out using the formula

A = \pi r^2

Here A is the area

r is the radius of the circle and

pi is a constant

given

Radius = r = 5

We have to find the area in terms of pi

So,

A = \pi r^2\\Putting\ r=5\\A = \pi *(5)^2\\A = 25\pi\ square\ feet

Hence,

The area of a circle with radius of 5 feet is 25π square feet

the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the numb
forsale [732]

Answer:

Number of pencils in stock = 1200

Average number of pencils sold by the manager per day = 24

Number of pencils that would be sold before reordering = 1200 - 500

                                                                                        = 700

Then

The number of days after which the manager will reorder = 700/24

                                                                                            = 29.16

So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.
