INITIAL VALUE HOPEFULLY IM SO SORRY IF ITS WRONG
Answer:
5,024 inches squared
Step-by-step explanation:
Since the area of a circle is pi r^2, we basically have to replace the r with 40, since it's the radius. Therefore when replaced, it would be pi(40)^2. This makes 1600pi. Pi is technically 3.14, so I multiplied 3.14 and 1600 to get 5,024 inches squared.
Answer:
25% of the people either buys a digital camera or a home theater receiver buth not both.
Step-by-step explanation:
The percentage of the customers that buy both a digital camera (D) and a home theather receiver (H) are included in the respective percentages (28% and 5%), so to calculate the percentage that buy only one of the items, we have to substract the percentage that buy both items from each of the percentages:
- If 28% of the people purchase a digital camera, and 4% buy both items, then 28-4=24% of the people buy only a digital camera.
- If 5% of the people purchase a home theater receiver, and 4% buy both items, then 5-4=1% of the people buy only a home theater receiver.
Then, we can add 24% and 1% and have that 25% of the people either buys a digital camera or a home theater receiver buth not both.
