Unit test, Part 2: Measurement of Two-Dimensional Figures Please help!!!

Mathematics
1 answer:
Vitek1552 [10]2 years ago
4 0

Answer:

Step-by-step explanation:

1. Area of the composite figure = Area of the sector + Area of rectangle

Area of sector = (θ/ 360) x \pir^{2}

From the figure,

θ = 30, and r = 65

Area of sector = \frac{30}{360} x \frac{22}{7} x 65 x 65

                        = 1 1065.55m^{2}

Area of rectangle = length x width

                        = 65 x 4

                       = 260 m^{2}

Area of the composite figure = 1 1065.55 + 260

                                                  = 11325.55

Area of the composite figure is 11326 m^{2}.

The total surface area is therefore:

A = 36 cm² + 4 (48 cm²)

A = 228 cm²

Mekhanik [1.2K]

Answer:

107.86 to 2 d.p.

Step-by-step explanation:

makes a triangle. 120 feet is the hypotenuse.

we want to find the opposite so we will use sine.

sin(x) = opp/hyp which means opp = sin(x)hyp.

opp = sin(64)120

opp = 107.86 to 2d.p.
