The first one would be 120 the second one would be 68
Answer:
<A = 35 degrees
Step-by-step explanation:
<A = x
<B = 2x
<C = 2x + 5
X + 2x + 2x + 5 = 180 degrees
5x + 5 = 180
5x = 180 -5
x = 175/5
x = 35
Answer:
79.6 cm^3
Step-by-step explanation:
The formula for the volume of a sphere is V = 4/3 πr³.
sphere A radius 2 cm so r[A] = 2 cm
sphere B radius 3 cm so r[B] = 3 cm
distance between the surfaces of the 2 spheres is 1 cm
To find volume of each sphere and the difference in volume:
pi r^2 * r - (1/3) pi r^2 * r = (2/3) pi r^3
8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
