Answer:
a) 3.507
b) 75.48
c) 78.41
Step-by-step explanation:
Problem A
The opposite side of the angle and the hypotenuse are involved in the question. Therefore you will be using the sine.
sin(26) = x / 8 Multiply both sides by 8
8*sin(26) = x Sin(26) = 0.4384
8*0.4384 = x Do the multiplication
3.507 = x
Problem B
The side adjacent and the hypotenuse are used in this problem. The angle is given, so you are working with the cosine.
Cos(58) = adjacent / hypotenuse
Cos(58) = 0.5299
0.5299 = 40/x Multiply both sides by x
0.5299 x = 40 Divide both sides by 0.5299
x = 40 / 0.5299
x = 75.48
Problem C
The opposite side and the adjacent side are involved and the angle is given.
Tan(71) = opposite / adjacent
tan(71) = 2.904
2.904 = x / 27 Multiply both sides by 27
2.904 * 27 = x Combine
x = 78.414

Answer:
36=b^2 or b=the square root of 36
Step-by-step explanation:
The sides of a square are all equal in length. To find the area of a square you can multiply the two sides together. Considering that they are the same length, you can just square one of the side lengths to get your answer. To find a side length you can take the square root of the area.
Surface area of the fig is 2350.9 sq m (approx).
Step-by-step explanation:
Given,
Diameter = 34 m
so, radius (r) = 17 m
Height of the cylinder (h) = 12 m
Slant height of the cone (l) = 20 m
To find the surface area of the fig
Surface area of the fig = surface area of cylinder + surface area of cone
Formula
Surface area of cylinder = 2πrh
Surface area of cone = πrl
So,
Surface area of cylinder = 2π×17×12 sq m = 408π sq m
Surface area of cone = π×17×20 = 340π sq m
Surface area of the fig = 408π+340π sq m = 748π sq m
= 2350.9 sq m (approx)
