First find the circumference of the patio.
Diameter is πd.
8 x 3.14 = 25.12
210º is approximately 58%.
Multiply 25.12 by .58 to get approximately 14.7 meters.
Hope this helps!
Answer: 4 months
Look at it this way: 6 books in a group. How many groups are there? well this is multiplication. Just add 6 a bunch of times until you get 24. You will add 6+6+6+6. There are 4 6's. This means, there are 4 months, with 6 books each month.
2b + 21 < 22
b is the unknown number so multiply it by 2 to get 2b then add 21, bring the less than sign and write the 22 after the less than sign
