Answer:
cylinder surface area = 201.06in²
surface area of cone = 56.56in.²
Step-by-step explanation:
cylinder surface area formula = 2πrh + 2πr²
refer the pic
cone surface area formula = πr ( r + √h² + r² )
refer the sec pic
surface area of the solid
= ( 201.06 + 56.56 ) in.²
= 257.62in.²
= 258in.²
Answer:
(a) or
(b) or
Step-by-step explanation:
Given
--- North Dakota
--- Cheyenne, Wyoming
Solving (a): Inequality to compare both temperatures
From the given temperatures, we can conclude that:
or
Because
i.e. 1 is greater than -2
or
i.e. -2 is less than 1
Solving (b): Inequality to compare the absolute values of the temperatures
We have:
The absolute values are:
By comparison:
or
Because
i.e. 2 is greater than 1
or
i.e. 1 is less than 2
