Answer:
Step-by-step explanation:
first it is about to delete your question and A. is 46 B. is 37
Ok so to answer this, we first need to figure out the area of both circles
we will use the formula A=πr²
so our two areas end up being 121π and 81π
now all we do is subtract the smaller from the larger
121π - 81π = 40π
shaded region = 40π
Answer:
Multiple choice questions = 5
True questions = 15
Step-by-step explanation:
Given that:
Total number of questions = 20
Total worth of point = 100
Multiple choice questions (M) = 11 points each
True false questions (T) = 3 points each
Hence,
M + T= 20 ____(1)
11M + 3T = 100 ____(2)
M = 20 - T
Using the relation in (2)
11(20 - T) + 3T= 100
220 - 11T + 3T= 100
220 - 8T = 100
-8Tf = 100 - 220
-8T = - 120
T = 120/8
T = 15
Mc = 20 - 15
Mc = 5
Multiple choice questions = 5
True false questions = 15
