4 0

Answer:

Option (D)

Step-by-step explanation:

Given quadrilateral in the circle is a cyclic quadrilateral.

By using the property of cyclic quadrilateral,

"Sum of each pair of opposite angles is 180°".

In the given cyclic quadrilateral,

d + 57° = 180°

d = 180 - 57

d = 123°

Similarly, c + 31° = 180°

c = 180° - 31°

c = 149°

Therefore, Option (D) will be the answer.

What is the volume of the prism
frosja888 [35]
The area of the triangular base is
  A = (1/2)bh
  A = (1/2)(5 units)(12 units)
  A = 30 units²

The "height" of the prism is 6 units, so the volume is
  V = (area of base)×(height)
  V = (30 units²)×(6 units)
  V = 180 units³

The appropriate choice is
  A. 180 units³

the volume of a cylinder is given by the formula v=3.14r^2h, where r is the radius of the cylinder and h is the height. suppose
photoshop1234 [79]

we know that

The volume of a cylinder is given by the formula

V=3.14 r^{2} h

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

r=x+8\\h=2x+3

Substitute the values in the formula above

V=3.14*(x+8)^{2}*(2x+3)

V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)

therefore

<u>the answer is</u>

The volume of the can is equal to

V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}
