Calculate the value of this cylinder and give your answer to 1 decimal place.

Volume = 2826cm^3 = (28.3 m^3) to 1dp.

Step-by-step explanation:

V=πr2h

V= π x 900 = 3.14 x 900 =2826cm^3

V=3.14 x (10)^2 x 9 = 2826cm^3

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
