Hello I really need some help I will give you BRAINLEST

 Choice B

Step-by-step explanation:

V = 4 pi * r^3 / 3

V = 4 (3.14) * 8^3 / 3

V = 12.56 * 512 / 3

V = 12.56 * 170.66

V = 2,143.57 cm^3

Hope this helped!  Please give brainliest.

oof cheaters cheat because they’re lazy that’s why i cheat xd

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
