The approximate percent increase in consumption from 1986 to 1997 is 20%
The complete question:
In 1997 the World Resources Institute estimated the world's proven oil reserves to be 1,000 billion barrels and the ultimately recoverable reserves to be 2,000 billion barrels. The table below shows the world consumption of oil from 1986 to 1997.
What was the approximate percent increase in consumption from 1986 to 1997?
<h3>How to calculate percentage increase in consumption</h3>
- 1986 consumption = 61.759 million barrels per day
- 1997 consumption = 73.700 million barrels per day
Percentage increase in consumption = (1997 consumption - 1986 consumption) / 1986 consumption × 100
= (73.700 - 61.759) / 61.759 × 100
= 11.941 / 61.759 × 100
= 0.19334833789407 × 100
= 19.3348337894072%
Approximately, 20%

Explanation:
How fast is the area of the spill increasing when the radius of the spill is 18 inches is d) 90pi in ^2/min.
<h3>Area of the spill</h3>
Area of the spill=S=πr²
dS/dr=(πr²)=2πr
Radius change with speed=dr/dt =2.5(m/s)
Area of the spill will increase with speed
dS/dt = dS/dr × dr/dt =2πr ×dr/dt
=2π×18×2.5
=282.74m²/s or 90pi in²/min
Therefore the correct option is D.
