A student determined that the area of the segment of c shown above is Asegment = 137.71 ft2. The student's work is shown below.

ivolga24 [154]

Answer:

Option D. The student did not use the correct formula to calculate the area of the segment

Step-by-step explanation:

step 1

Find the area of the isosceles triangle

Applying the law of sines

$A=\frac{1}{2}(12^{2})sin(60\°)=62.35\ ft^{2}$

step 2

Find the area of the sector

The area of the sector is 1/6 of the area of the circle

$A=\pi r^{2}/6$

substitute the value

$A=(3.14)(12)^{2}/6=75.36\ ft^{2}$

step 3

Find the area of the segment

The area of the segment is equal to the area of sector minus the area of triangle

$A=75.36\ ft^{2}-62.35\ ft^{2}=13.01\ ft^{2}$

therefore

The student did not use the correct formula to calculate the area of the segment

A box in the shape of a cube has a volume of 64 cube inches. What is the length of a side of the box

Naily [24]

The volume of a cube can be expressed as

Let V = volume

Let a = side length

V = a^3

We need to solve the formula to isolate the variable a. First, we must cube root each side.

∛(V) = a. With our new formula, we plug in 64 cube inches into V.

∛(64) = a.

4 = a.

The length of one side on our cube is 4 inches.
