The measure which is closest to the volume of Luis's globe is; 6301.2in³
<h3>Volume of a sphere</h3>
If the circumference of the globe along the equator is 72inches along the equator;
Hence, the radius of the globe can be evaluated as;
r = 11.46in.
On this note, the Volume, V of the globe is;
- V = (4/3) × 3.14 × 11.46³
V = 6301.2in³

Answer:
d.
Step-by-step explanation:
if x varies directly as y,
x = ky
8 = 12k
12k = 8
k = 8/ 12
k = 2/3,
x = 2/3 y
now substitute the value of any of the numbers of each pair, and check if it works:
for e.g, find x when y = 15
x = 2/3y
x = 2/3 × 15
x = 10
since you obtain x = 10 when y = 15, the pair is a possible corresponding value of x and y. now do the same for the rest .
ii) x = 2/3y
x = 2/3 × 3, when y = 3
x = 2
hence, this is also a possible pair of x and y values.
iii) x = 2/3y
x = 2/3 × 9 when y = 9
x = 6
again, a possible pair of x and y values.
iv) x = 2/3y
x = 2/3 × 20 when y = 20
x = 40/3
here, when y = 20, x is not 15. it is 40/3.
thus, it can be determined that this is not a possible pair of x and y values.

Answer:
64.5%
Step-by-step explanation:
Initial amount N° = ?
Remaining amount after decay = N = ?
k = decay constant = 0.00012 
t = time = 3650 year
fraction remaining will be N/N°
From the decay equation, N = N°
N/N° =
N/N° = 
N/N° = 
N/N° = 0.645 = 64.5%
