Step-by-step explanation:

step 1. the area of a circle is A. A = (pi)r^2.

step 2. if the diameter is 8 cm then the radius is 4 cm.

step 3. A = (pi)4^2

step 4. A = 16(pi) = 50.24 cm.

Answer:

Step-by-step explanation:

A=\pir^{2}                            Diamter is half the radius so the radius is 4

A= 3.14 times 4^{2}                       4^{2}= 16

A= 3.14 times 16

A=50.24

rounded answer will be 50.2

Ace Cars says they will pay Jim a 10% commission on the sale price of each car. Budget Cars says they will pay him $500 per week
Arisa [49]

Answer:

  $20,000

Step-by-step explanation:

You can quickly figure this by recognizing that the difference in commission must be the same as the base salary:

  2.5%(car price) = $500

  car price = $500/0.025 = $20,000

__

If you prefer, you can get there with equations.

At Job 1, the pay is ...

  y = 10%×(car price)

At Job 2, the pay is ...

  y = 7.5%×(car price)

Setting the equal (the two opportunities pay the same), we have ...

  0.10(car price) = 500 +0.075(car price)

  0.025(car price) = 500 . . . . . . . . subtract 0.075(car price)

  car price = 500/0.025 = 20,000 . . . . divide by 0.025

Jim would have to sell a $20,000 car each week for the jobs to pay the same.

the utility industry has 428.5 thousand jobs in 2010 and is expected to decline at an average rate of 3 thousand jobs per year f
Aleksandr-060686 [28]

Answer: 7%

Step-by-step explanation:

Given: Initial jobs = 428.5 thousand

Average rate of declining of jobs  from 2010 to 2020 =  3 thousand jobs per year

From 2010 to 2020 , there are 10 years.

Total jobs declines till 2020 = 10 x (3 thousand)

= 30 thousand  (Change in jobs)

Now, utilities percent change for 2010 to 2020​ : \dfrac{change \  in \  job\  numbers}{Initial\ jobs}\times 100

=\dfrac{30}{428.5}\times100\\\\\approx7.00\%

Utilities percent change for 2010 to 2020 = 7 %
