Find Volume for the cones. Round to the nearest TENTH. (A) Radius of 2 in, and a height of 4 inches (B) Diameter of 6 m, and a h
Aleksandr-060686 [28]

Answer:

A. 16.8 in³

B. 28.3 m³

C. 65.4 in³

Step-by-step explanation:

The volume of a cone is given as:

V = ⅓ * pi * r² * h

Where r = radius of base of cone

h = height of cone

A. Radius = 2 inches, height = 4 inches

It's volume is:

V = ⅓ * pi * 2² * 4

V = 16.8 in³

B. Diameter of 6 m, and a height of 3 m

It's diameter is 6 m, therefore, it's radius is:

r = d / 2 = 6 / 2 = 3 m

It's volume is:

V = ⅓ * pi * 3² * 3

V = 28.3 m³

C. Diameter of 5 in, and a height of 10 in

It's diameter is 5 in, therefore, it's radius is:

r = d / 2 = 5 / 2 = 2.5 m

It's volume is:

V = ⅓ * pi * 2.5² * 10

V = 65.4 in³

On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). What is the length of Side RT
andriy [413]
Answer : 7 units

There are two ways you can solve this problem:

1st way - Subtract the T's x coordinate by r's x coordinate.

1-(-6) = 1+6 = 7

2nd way - Graph the points than count the units between them.

What is the measure of arc QR?
riadik2000 [5.3K]

Answer:

answer is the third choice : 104

Step-by-step explanation:

Inscribed Angle Theorem

If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.

so the intercepted arc is TWICE the measure of an angle inscribed in a circle

1. A central angle is an angle with endpoints located on a circle's circumference and vertex located at the circle's center. A central angle in a circle determines an arc.

2. An inscribed angle is an angle formed by three points on the circle's circumference.

Angle at the Center Theorem: An inscribed angle is half of the central angle (if they determine the same arc).

In your case angles:

1. ∠QSR is insribed (determines the arc QR);

2. ∠QTR is central (determines the arc QR).

Then by Angle at the Center Theorem, m∠QTR=2m∠QSR=2·52°=104°. Arc QR has the same measure as central angle QSR.
