Preston measured the button on his shirt. Then he calculated that it has an area of 50.24 square millimeters. What is the button
soldi70 [24.7K]
*note: for this problem you have to round a few values. I rounded to 2 decimal places, but your answer could be different if you have to round to more/less than 2 decimal places

Answer: Diameter = 8 millimeters


Buttons are circles, so we will use the formula for area of a circle:

A = πr^2

We are solving for the diameter, which is 2 times the radius:

d = 2r

So now we plug in what we know.
The area A = 50.24 square millimeters, therefore we plug it in and simplify:

50.24 square millimeters = πr^2

50.24/π = r^2

15.99 = r^2

squareroot(15.99) = r

r = 4 millimeters

Now we use the radius to calculate the diameter.

r = 4 millimeters

d = 2r

d = 2(4)

diameter = 8 millimeters

4. triangle FBT is similar to triangle ADQ with a scale factor of 5/3. Complete the table below.
Bogdan [553]

Triangle FBT is similar to triangle ADQ with a scale factor of 5/3. AD = 9; BF = 15, DQ = 6; BT = 10, FT = 21; AQ = 12.6

∠F = ∠A = 40°, ∠Q = ∠T = 55°, ∠B = ∠D = 85°

<h3>What are similar triangles?</h3>

Similar triangles are triangles that have the same shape and the ratio of their corresponding sides are in the same proportion. Corresponding angles are equal.

triangle FBT is similar to triangle ADQ with a scale factor of 5/3.

AD = 9; BF = 9 * 5/3 = 15

DQ = 6; BT = 6 * 5/3 = 10

FT = 21; AQ = 21 * 3/5 = 12.6

∠F = ∠A = 40°, ∠Q = ∠T = 55°, ∠B = ∠D = 85°

Answer:

  {(0, −5), (2, 9), (−3, −26)}

Step-by-step explanation:

You only need to try the first point in each set to eliminate the wrong answers.

a: 7(-5)-5 = -40 ≠ 0

b: 7(2)-5 = 9 ≠ 7

c: 7(0)-5 = -5 . . . matches given point

d: 7(1)-5 = 2 ≠ 3

The third choice is the correct one: {(0, −5), (2, 9), (−3, −26)}.
