If a windshield wiper covers an area of approximately 200 square inches when it rotates at an angle of 84°, find the length of the wiper to the nearest tenth of an inch. The length of the wiper is approximately inches.

≈ 16.5 in

Step-by-step explanation:

r- is the length of the wiper

Area of circle= πr²

Area of 84° sector = πr²*84/360= 200 in²

3.14r²*84/360= 200

r²= 200*360/84*3.14

r²= 273

r= √273

r≈ 16.5 in

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
