Step-by-step explanation:
We can use PEMDAS for this
in PEMDAS exponents comes 2nd and in the expression we have exponents so lets solve that first
8^2=64
next is multiplication
so
64*3.14=200.96
200.96*23=4622.08
to round to the nearest tenth we need to look right of the tenths place
since there is an "8" we can round up to "1"
4622.1
