5 0

Answer:

approximately 10

Step-by-step explanation:

Volume = 1/3h times \pi times radius square

1570 = 1/3 x 15 x 22/7 x r^{2}

1570 = 5 times \frac{22}{7} times r^{2}

1570 = 15.71r^{2}

\frac{1570}{15.71} = \frac{15.71 r^{2}}{15.71}

99.9 = r^2

\sqrt{99.9} = r

≅10

The area of parallelogram WXYZ is approximately 45 square units.
neonofarm [45]

Answer:

Option (4)

Step-by-step explanation:

Area of a triangle = \frac{1}{2} (a.b.\text{Sin}\theta)

Where a and b are the sides of a triangle and θ is the angle between the sides a and b.

By this rule,

Area of ΔWZY = \frac{1}{2}(\text{WZ}).(\text{YZ}).\text{Sin}(115)

45 = \frac{1}{2}(\text{YZ}).(10).\text{Sin}(115)

9 = (YZ).Sin(115)°

YZ = \frac{9}{\text{Sin}(115)}

YZ = 9.93

Perimeter of parallelogram WXYZ = WX + XY + YZ + WZ

                                                         = 9.93 + 10 + 9.93 + 10

                                                         = 39.86

                                                         ≈ 40 units

Therefore, perimeter of the parallelogram is 40 units.

Option (4) is the answer.
