Yes because 6x75=450
6x70=420
6x80=480
So 420+30=450
450+30=480
Answer:
21/24
Step-by-step explanation:
Answer:
Part 1= Pi * R Squared
Part 2: 50.27
Part 3: 78.54
Part 4: 28.27
Step-by-step explanation:
Part 1: Memorize the formula
Part 2: 8 feet diameter = Pi * 4 squared. 8 feet is the diameter so the radius is 4. 4 squared is 16. 16 * pi = approximately 50.27, but is 50.24 if 3.14 is used as pi.
Part 3: Pi * 5 squared since 10 is diameter. 25 * pi which is close to 78.54, but is 78.5 is 3.14 is used for pi.
Part 4: I subtracted Part 3 from Part 2.
If you're doing kilometers per HOUR then the answer would be 2.25 just do 1991.25 divided by 885.
ANSWER : 2.25
