The answer is: 18.823
Rounded off to how many decimal places (dp) !... 0.795 (3 dp) 0.80 (2dp)
To 4 DP, 62.1935 To 3 DP, 62.194 To 2 DP, 62.19 To 1 DP, 62.2
7.874 DP (rounded)
It is rounded to 15.3913
It is: pi*8 = 25.133 feet rounded to 3 dp
706.142 square units rounded to 3 dp
15.54 is rounded to 2 decimal places and it makes little sense to express a number from 2 dp to 3 dp but, since you have asked, the answer is 15.540
2.224 (to 3 dp)
There are about 8.296 square feet rounded to 3 dp
radius = 11.304/(2*pi) = 1.799 units rounded to 3 dp
circumference = pi*22.5 = 70.686 cm rounded to 3 dp
pi*1.52 = 7.069 square cm rounded to 3 dp
