Answer:
None of the options are correct
О E. 289.2 cm
Step-by-step explanation:
Volume of a cylinder = v = л r² h
л = 3.1416 (aprox)
r = radius
h = height
8177 = 3.1416 * 3² * h
8177 = 3.1416 * 9 * h
8177 = 28.2744 * h
8177/282744 = h
h = 289.2 cm
50 meters
Explanation
you can easily solve this by using a rule of three.
Step 1
Let

x represents the length of the actual lawn
then

the proportion is the same, so
Step 2

so, the length is 50 meters
The difference is
302
-129
_____
173
to prove this
173
+129
_____
3+ 9 is 12 so the unity is 2 and you plus 1 to the tenth; 7 + 2 is 9 but if you plus the number that remained in the unity is 10 so the the tenth is 0 and you will plus 1 to the hungred, 1+1 is 2 but if you plus the 1 that remained in the tenth is 3, so if we put them all together it will be 302
i hope i helped you
