To find the surface area of a cylinder, add the areas of the two circles and the rectangular piece connecting them
area of circle: A = pi(r)^2
A = pi(7)^2
A = 49pi
area of rectangle: A = length X width
the length is the circumference of the circle
C = 2pi(r)
C = 2pi(7)
C = 14pi
multiply 14 pi by the width 5
area of rectangle: 70pi
add the areas of the two circles and the rectangle:
49pi + 49pi + 70pi = 168pi
ANSWER: 168pi
for the decimal if you use pi on the calculator then the answer is 527.8
but if u multiply by 3.14 the answer is 527.5
hope this helps!
Answer:
B
Step-by-step explanation:
y=x+2. let it eq 1
put y= - 2 and x=-4 in eq 1
-2 = -4+2
-2= -2
now put x= -3 and y= -1 in eq 1
-1 = -3+2
-1 =-1
now put x= -2 and y=0 in eq 1
0 = -2+2
0=0
now put x= -1 and y=1 in eq 1
1 = -1+2
1=1
