doubling the radius will have a greater effect
v of cylinder=pi x square of radius x hieght
lets take an example,r=2,h=2
v=8pi
doubling the hieght,h=4
v=16pi ie twice the initial volume
doubling the radius,r=4
v=pi x 16 x 2
=32 pi ie four times the initial volume
therefore radius makes a bigger difference
Answer:
D). Combat the overuse of asphalt and concrete surfaces.
Explanation:
Urban Heat is characterized as the circumstance in which a particular urban area has a considerably increased temperature because of specific human activities. As per the question, the most adequate strategy to assist a city in fighting the battle against the increasing 'urban heat island' would be to '<u>avoid the excessive use of surfaces made of concrete and asphalt</u>.' The key reason behind this is that 'asphalt and concrete surfaces tend to possess an extremely higher heating capacity' and thus, it absorbs heat from the sun and causing the land temperatures to reach higher till 60° celsius. Therefore, preventing the overuses of such surfaces would be the most adequate strategy to keep the temperatures in control. Hence, <u>option D</u> is the correct answer.
