Area of a circle = PI x r^2
Area of sheet = 22/7 x 18^2 = 1,018.29 square cm.
Area of small circle = 22/7 x 4.5^2 = 63.64 square cm.
There are 2 small circles so total area of the circles are 63.64 x 2 = 127.28 square cm.
Area of rectangle = l x w = 4 x 1 = 4 square cm.
Total area of cutouts = 127.28 + 4 = 131.28 square cm.
Area of sheet left, subtract area of cutouts fro area of sheet:
1018.29 - 131.28 = 887.01 square cm.
Round everything as needed.
Answer:
B.
Step-by-step explanation:
Have a great day!
The major advantage of exponential notation is that it simplifies a number into a more readable form, so we don't have to count all the zeros every time we look at it / calculate it. It helps us to identify big numbers as small decimals which we are more familiar with.
CHOICE 1 $1250+5.5% of sales
$5000x0.055=$275+1250=$1525
$10,000x0.055=$550=1250=$1800
CHOICE 2 $2600=2% of sales
$5000x0.02=$100+2600=$2700
$10000x0.02=$200+2600=$2800
So even though more is earned through percentage of sales in CHOICE 1, it doesn't make up for the larger monthly salary of CHOICE 2
