A circle has a diameter of 10 cm. What is the best approximation of its area? Use 3.14 for pi.....you need radius not diameter in the formula! (Hint: A = π r2 )

78.5 sq cm


314 sq cm


31.4 sq cm


15.7 sq cm

Answers

Answer 1

Answer:

If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²

Then you do r * π *r which would be 78.5. so C is your answer.

Step-by-step explanation:

Answer 2
This 15.7 is the correct answer

A stadium can seat 16,00 people at full capacity

a.If there are 13,920 people in the stadium, what percentage of the capacity is filled?
Explain or show your reasoning

Answers

Answer:

87% full

Step-by-step explanation:

To find the solution:

Use the equation p·x=y where x = 13,920 and y = 16,000Since you are trying to find the percent, divide both sides of the equation by 13,920. p · 13,920(÷13,920) = 16,000(÷13,920)The step above cancels out the 13,920 leaving you with the answer. p=0.870.87 = 87%

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.

The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.

The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.

Devin wants to use his 12% employee discount to buy a video game that is priced at $57.80. A 8.75% sales tax is applied to the discounted price. What will be the total cost of the video game, including the sales tax?

Answers

Answer:

43.73

Step-by-step explanation:

use a calculater

First you need to find the price of the video game after Devin’s employee discount. To do this you multiply the original price times the discount:

$57.80 * 0.12 = $6.94

Now subtract the discount from the original price:

$57.80 - $6.94 = $50.86

Now we need to multiply the discounted price and the sales gas rate to see how much taxes will be added to our purchase:

$50.86 * 0.0875 = $4.45

Finally we add our discounted price plus the sales tax to find the total cost of the video game after the employee discount:

$50.86 + $4.45 = $55.31

Amanda purchased a pair of shoes for $32.00 and two blouses
for $15.00 each. If the sales tax is 8.5%, what was the total
amount Amanda paid?

Answers

Answer: 3.68

Hopefully is helps

Answer: $67.27

Step-by-step explanation:

Add: $15.00+$15.00 : $30.00. Because she purchased two of them.

Then add the total to $32.00, which = $62.00.

Writing the proportion: 8.5/100  x/62.00

Multiply the sales tax by your total amount = 8.5*62.00=527.00

Then divide it by 100= 527.00/100= $5.27. <-- ( sales tax amount )

Add the sales tax to $62.00 = 67.27

Answer: $67.27
