Answer:
<h2>
62.832 mi.²</h2><h2>
</h2>
Step-by-step explanation:
surface area = 2πrh + 2πr²
where r = 2 miles radius
h = 3 miles
<u>plugin values into the formula</u>
surface area = 2πrh + 2πr²
= 2π (2) 3 + 2π (2)²
= 37.699 + 25.133
= 62.832 mi.²

Answer:
25°C = 77 degree Fahrenheit.
Step-by-step explanation:
In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.
where C = degree centigrade and F = degree Fahrenheit
Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,
We will plug in the value of C in the expression,


F = 45 + 32
F = 77
Therefore, 25°C = 77 degree Fahrenheit will be the answer.
