Which of the following could be used to calculate the area of a sector in the circle shown below
lara [203]

Answer:

Therefore the Last option is correct

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

Step-by-step explanation:

Given:

Radius = r = 8 in

θ = 42°

To Find:

Area of Sector = ?

Solution:

We know that

\textrm{Area of Sector}=\pi (Radius)^{2}\times \frac{\theta}{360}

Substituting the given values in the formula we get

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

Which is the required Answer.

Therefore the Last option is correct

\textrm{Area of Sector ACD}=\pi (8\ in)^{2}\times (\frac{42}{360})

(03.02 MC)
kotykmax [81]

Answer:

The coordinates of J are missing.  Plus, I don't see options for the conclusions.  I made an imaginary point J, which you could correct to form the proper triangle.

Step-by-step explanation:

See the attachment.  Plot all the vertices, including a corrected point J and draw the resulting triangle.  It might be that AJKL is a slightly smaller, shifted version of AGHI.  Enter the correct coordinates and then compare.

The volume of a sphere is 2254 pi m^3 what is the surface area of the sphere to the nearest 10th
Advocard [28]
By definition. The volume of the sphere is:
 V = (4/3) * (pi) * (r ^ 3)
 Where,
 r: radius of the sphere.
 Substituting values:
 2254 pi = (4/3) * (pi) * (r ^ 3)
 Clearing the radio we have:
 r ^ 3 = (3/4) * (2254)
 r = ((3/4) * (2254)) ^ (1/3)
 r = 11.91255883
 Then, the surface area is:
 A = 2 * pi * r ^ 2
 Substituting values:
 A = 2 * 3.14 * (11.91255883) ^ 2
 A = 891.6 m ^ 2
 Answer:
 
The surface area of the sphere is:
 
b. 891.6 m ^ 2
