Midpoint question:):)
Answer: it’s 20
Step-by-step explanation: QR= 6, RS= 6, ST= 8 because 14-6=8
Answer:
The answer is 20
Step-by-step explanation:
If R is in the middle of s and q and it equals 6, then you just have to multiply it by 2. You will get 12 for QS. Now to find the whole thing, subtract 6 from 14 to get 8 and add 8 to 12 to get 20.
20 is your answer.

A right circular cone has a height of 10 centimeters and a base of 9cm. What is the volume of the cone
Answer:
19cm
Step-by-step explanation:
The volume of the give cone is 21.40 cm³
What is a cone?A cone is a shape formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex). The distance from the vertex of the cone to the base is the height of the cone.
Given that, A right circular cone has a height of 10 centimetres and a base of 9 cm.
The circumference of the base is 9 cm
Therefore, 2πr = 9
r = 9/3.14×2
r = 1.43 cm
Volume of a cone = πr²h/3
V = 3.14(1.43)²10/3
V = 21.40 cm³
Hence, The volume of the give cone is 21.40 cm³

A cylinder has a 21.02 in. diameter. The linear speed of a point on the cylinder's surface is 18.12 ft/sec. What is the angular speed of the cylinder, in revolutions per hour?
Answer:
11860.22 rev/hour
Step-by-step explanation:
The diameter if a cylinder, d = 21.02 inches
Radius, r = 10.51 inches
or
r = 0.875 feet
The linear speed of a point on the cylinder's surface is 18.12 ft/sec.
We need to find the angular speed of the cylinder.
The relation between the linear speed and the angular speed is given by :
[tex]v=r\omega[/tex]
Where
[tex]\omega[/tex] is angular speed
[tex]\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s[/tex]
or
[tex]\omega=11860.22\ rev/hour[/tex]
So, the required angular speed of the cylinder is 11860.22 rev/hour.
