We are given
area of sphere is 200.96cm^2
it means that we are given surface area
so, we can use surface area formula

where S is surface area
r is radius
so, firstly we need to find radius or r

we can solve for r

now, we can find volume

we can plug r

now, we can find volume

Answer:
A) R = 1900 -24t
B) 1684 billion barrels
C) 79.17 years
Step-by-step explanation:
<h3>A)</h3>
Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.
R = 1900 -24t
__
<h3>B)</h3>
For t=9, the reserves will be ...
R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels
__
<h3>C)</h3>
The reserve will be 0 when ...
0 = 1900 -24t
24t = 1900 . . . . . add 24t
t ≈ 79.17 . . . . divide by 24
Reserves will be gone in about 79.17 years.
Answer:
Step-by-step explanation:
19% of 72 = about 14%
42% of 16 = about 7%
47% of 118 = about 55%
67% of 296 = about 198%
It's 65. Because you add the other angles and get 90+25 and get 115. 180 -115 = 65.
