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.

Two vertices of a right triangle have coordinates ( 9 , 1 ) and (;6 , - 1 ) Select each ordered pair that could be the coordinat
Serjik [45]

Option A: (9,-1) is the third vertex

Option B: (6,1) is the third vertex.

Explanation:

The two vertices of the right triangle are (9,1) and (6,-1)

The third vertex of the right triangle can be determined by plotting the points in the graph.

Option A: (9,-1)

By plotting the points (9,1), (6,-1) and the third vertex (9,-1) in the graph, the the hypotenuse of the triangle passes through the vertices (9,1) and (6,-1)

The legs of the triangle passes through the vertices (9,1), (9,-1) and (6,-1), (9,-1)

Hence, the third vertex (9,-1) forms a right triangle.

Therefore, Option A is the correct answer.

Option B: (6,1)

By plotting the points (9,1), (6,-1) and the third vertex (6,1) in the graph, the hypotenuse of the triangle passes through the vertices (9,1) and (6,-1)

The legs of the triangle passes through the vertices (9,1), (6,1) and (6,1) , (6,-1)

Hence, the third vertex (6,1) forms a right triangle.

Therefore, Option B is the correct answer.

Option C: (1,-1)

By plotting the points (9,1), (6,-1) and the third vertex (1,-1) in the graph, we can see that the three vertices does not make a right angled triangle.

Hence, the third vertex (1,-1) does not form a right triangle.

Therefore, Option C is not the correct answer.

Option D: (6,9)

By plotting the points (9,1), (6,-1) and the third vertex (6,9) in the graph, we can see that the three vertices does not make a right angled triangle.

Hence, the third vertex (6,9) does not form a right triangle.

Therefore, Option D is not the correct answer.
