First find the answer without decimals
√225= 15
2.25 has two decimal places, so therefore the square root must contain 1 decimal place.
√2.25= 1.5
Final answer: 1.5
ps -1.5 is also correct but I'm not sure if that's what your teacher wants.
Step-by-step explanation:
Diameter (d) = 22 inch
Radius (r) = d/2= 22/2 = 11 inch
π = 3.14
Now
Circumference = 2πr
= 2* 3.14 * 11
=69.08 ich
And now
Area = πr²
= 3.14 * 11²
= 379.94 inch²
The leftmost of the the two digits is 10x that of the right one.
