Answer:
3620.57
Step-by-step explanation:
Given: Stacy hits the jackpot one day at the gumball machine and won 4 gumballs, radius of each gumball is 6 mm
To find: Total volume of all 4 gumballs
Solution:
Gumball is Spherical
Volume of Sphere = (4/3)πr³
r = Radius of Sphere
r = 6mm
Volume of 1 gumball = (4/3)π * 6³
= 288π mm³
Volume of 4 gumballs = 4 * 288π
= 1152π mm³
using π = 22/7
= 3,620.57 mm³
or using π = 3.14
= 3,617.28 mm³
Volume of 4 gumballs = 288π mm³ ≈ 3,620 mm³
X= 36 for the first problem.
X= 48 for the second problem.
X= 80 for the third problem.
I=PRT
Interest=I
P=principal
R=rate in decimal
T=time in years
given
asuming 640 is the principal and not the interest
P=640
R=3%=0.03
T=2
I=640*0.03*2
I=19.2*2
I=38.4
interst=$38.40
