For each of the problems, twice the angle formed by the chords is equal to half the sum of the angles of the arcs.

So, for the first problem, we have 94 \cdot 2 = x+103, so x = 188 - 103 = 85. 

For the second, 102 \cdot 2 = x + 118, so x = 204 - 118 = 86.

For the last problem, 106 \cdot 2 = x + 88, so x = 212 - 88 = 124.

Feel free to comment below if you have any questions!

Answer:

y = 20/3 * x + 125/3

Question 4 : 3 hours study for score 55 (?)

Step-by-step explanation:

2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.

y = mx + b

m = (75 - 55) / (5 - 2) = 20/3

b = y - mx = 55 - (20/3) * 2 = 125/3

Equation: y = 20/3 x + 125/3

The Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924 \pi square fee
Salsk061 [2.6K]

The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.

<h3>What is the volume of the sphere?</h3>

The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.

Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.

The volume of the dome will be calculated as below:-

SA = 13.924π

2πr² = 13.92π

r = √6.96

r = 2.63 feet

Volume = 2 / 3 πr³

Volume = ( 2 / 3 ) π ( 2.63)³

Volume = 12.24π cubic feet

Therefore, the volume of the spherical dome will be 12.9π cubic feet.
