Given:
Radius of the base of the cone = 12 in.
The slant height of the cone = 15 in.
To find:
The lateral surface area of the given cone.
Solution:
The lateral surface area of the cone is:

Where, r is the radius of the base of the cone and h is the slant height of the cone.
Putting
, we get


The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.
Answer:
Order the numbers from least to greatest.
75, 83, 89, 94, 98, 101, 105, 108, 111, 122, 125, 130
Minimum is 75
Q1 is 91.5
The median is 103.
Q3 is 116.5
Maximum is 130
Now, look at the answer choices.
B has the incorrect median
D has incorrect Q1.
A has incorrect Q3.
C is the answer.
Answer:
120
Step-by-step explanation:
All the angles should add up to equal 180 so,
28 + 32 + ? = 180
60 + ? = 180
180 - 60 = 120
