Answer:
The right answer is A = 49.6 π ft^2
Step-by-step explanation:
<em><u>(Let pi = 3.1415926535898)</u></em>
<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>
<em>So if r = 4 ft</em>
<em>and h = 2.2 ft</em>
<em>A= 2π(4)(2.2)+2π(4)^2</em>
<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>

Answer:
C
Step-by-step explanation:
a is defined first as 5. So a = 5.
b is defined after the circle b = -2
a^2 = 5^2 = 25
B^4 =(- 2)^4 = 16
Therefore sqrt(a^2 * b^4) = sqrt(25 * 16) = sqrt(400) = 20
The answer is C
Answer:
Step-by-step explanation:
what is the value of a in a/5 + 3= 8
a/5 + 3= 8
a/5 = 8 - 3
a/5 = 5
a = 5 * 5
a = 25
No that is false very false
