Answer:
Th correct option is D. 13
Therefore the value of x is 13.
Step-by-step explanation:
Given:
measure of an intercepted arc = 86°
Center Angle = 86°
measure of the inscribed angle creating the intercepted arc= (3x+4)°
Angle Inscribed in arc = (3x+4)°
To Find:
value of x = ?
Solution:
Inscribed Angle Theorem:
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Substituting the values we get
Therefore the value of x is 13.

A & B
Step-by-step explanation:
A) V = pi×r²×h
= 3.142 × 8² × 5 = 1005.44 cm³
B) V = ⅓ × 18×16 × 12 = 1152 cm³
C) V = ½×5×3 × 7 = 52.5 cm³

What is the interquartile range of this data set 2,5,9,11,18,30,42,48,71,73,81
katrin [286]
First, find the median: 30
Then, find the median of the 2 sides from 30 (Q1 and Q3)
The middle value between 2 and 18 is 9. The middle value between 42 and 81 is 71. Now, just subtract 71-9.
The IQR is 62 :)
