A CAMPGROUND HAS TENTS IN THE SHAPE OF A CYLINDER MOUNTED BY HALF-SPHERE DOME. TENT HAS A HEIGHT OF 6 FT. AND BASE RADIUS OF 2 FT. WHAT IS TOTAL AMOUNT OF AIR IN THE TENT IN CUBIC FT.? A) 88π/3 B) 8π C) 20π D)40π/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)

21/58.

hope to be marked brainliest
