Answer: 153.86
Step-by-step explanation:
a=nr^2
A= 3.14 * 49
A= 153.86
Draw one ten, (If you have to draw ones, draw 3 of those) and the new fact is 10 + 3. (That equals 13, if you need that.)
The answer might be 7,8,9
Answer:
Approximately 42.
Exact sum is 42 13/40.
Explanation:
Estimate 11 3/8: 11
Estimate 9 7/10: 10
Estimate 21 1/4: 21
Add them together: 42.
11.375 + 9.7 + 21.25 = 42.325
I made them into decimals and then will convert it into fraction.
42.325 = 42 13/40
Hope this helps!
