Answer: = 11.88
This is a 3 step / 4 show workings.
10.7 + Percentage increase = 11%
10.7 + (11% × 10.7) = 10.7 + 11% × 10.7
(1 + 11%) × 10.7 = (100% + 11%) × 10.7
111% × 10.7 = 111 ÷ 100 × 10.7
111 × 10.7 ÷ 100 = 1,187.7 ÷ 100
11.877 ≈ 11.88
V(t) = πr^2h
V'(t) = π(2rr'h + r^2h')
V'(t) = π(2(5)(-2)(7) + 5^2(8)
V'(t) = π(-140 + 200)
V'(t) = 60π in^3
The answer for this is 37.5. I can't show the work because i searched it up on Google.
actually none of them since 212 is the biggest number and should be at the end but none of the answers say so
