Answer:

  18.8 m²

Step-by-step explanation:

The area of a sector is given by the formula ...

  A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians

To convert an angle in degrees to one in radians, multiply by π/180°.

Your 135° sector has an area of ...

  A = (1/2)(4 m)²(135°)(π/180°) = 6π m²

  A ≈ 18.8 m²

The volume of the cone is 130 units^3. Solve for x.<br> Height: 13<br> Radius: x
Gwar [14]
V=(1/3)hpir^2
v=130
h=13
r=x

130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
