Answer:
28 
Step-by-step explanation:
V = 4 * 1 * b = 8
b = 2
SA = 2(4 + 1) * 2 + 2(4)1)
SA = 28

Answer:
   the point is (3, 3) . . . . . . y = 3
Step-by-step explanation:
Write the point-slope equation of the line through the point you know. Then evaluate that equation for x=3 to see what the value of y is.
Point-slope form:
   y = m(x -h) +k . . . . slope m through point (h, k)
   y = -1/2(x -9) +0 . . . . line with slope -1/2 through point (9, 0)
For x=3, the value of y is ...
   y = -1/2(3 -9) + 0 = -1/2(-6) = 3
The value of y is 3.

<h3>What are trigonometric ratios?</h3>
Trigonometric Ratios are values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.
Sin θ: Opposite Side to θ/Hypotenuse
Tan θ: Opposite Side/Adjacent Side & Sin θ/Cos 
Cos θ: Adjacent Side to θ/Hypotenuse
Sec θ: Hypotenuse/Adjacent Side & 1/cos θ
Analysis:
tan θ = opposite/adjacent = 7/4
opposite = 7, adjacent = 4.
we now look for the hypotenuse of the right angled triangle
hypotenuse =  =
 =  =
 = 
sin θ = opposite/ hyp = 
Rationalize,  x
 x  =
 = 
But θ is in the third quadrant(180 - 270) and in the third quadrant only tan and cot are positive others are negative.
Therefore, sin θ = - 
cos   θ  = adj/hyp = 
By rationalizing and knowing that cos  θ  is negative, cos θ  = -
cot θ  = 1/tan θ  = 1/7/4 = 4/7
sec θ  = 1/cos θ  = 1/ = -
 = -
cosec θ  = 1/sin θ  = 1/ =
 =
