Find the area of a semicircle.
Use a = 3.14

Answers

Answer:

157.08cm²

Step-by-step explanation:

pls brainliest

Answer:

157 cm

Explanation:

First you need to find the radius so you divide 20 by 2 (20 ÷ 2). Which will give you, our radius of 10. You take that radius and square it so 10 x 10. You will get a product of 100. Then you multiple the 100 by pi (100 x 3.14) and you will get 314. Since it's a semicircle you need to cut this 314 in half (314 ÷ 2 = 157).

3. The mode it what number repeats ( -4)
4. The range is the subtracted greatest from the least (-1)

2. The median is the number in the middle. If there are two middle numbers, add those together and divide by two.
3. The mode is the number that repeats the most.
4. The range is the difference between the least and greatest number. Just take the greatest number and subtract it by the least number and you’ll have your answer.

Step-by-step explanation:

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his stock in Company B was worth $1000. The stock in Company A has increased 20% since last year and the stock in Company B has increased 22%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Answer:

20.7%

Step-by-step explanation:

Amount of stock increased in Company A = 20% of 1790

= 0.20 * 1790 = $ 358

Investor's stock in company A this year = 1790 + 358 = $ 2148

Amount of stock increased in Company B = 22% of 1000

= 0.22 * 1000= $ 220

Investor's stock in company B this year = 1000 + 220 = $ 1220

Total amount in investor's stock account = 2148 + 1220 = $ 3368

Increased amount = 3368 - 2790 = $ 578

Increase percentage = [tex]\frac{578}{2790}*100[/tex] = 20.71

= 20.7%

20.7%
