This set focuses on geometry and data analysis—two areas where careful setup and clean algebra can earn quick points.
Question 1
A circle has radius 6. What is its area?
A. 12π
B. 18π
C. 36π
D. 72π
Step-by-step solution
Use the area formula A = πr^2.
Substitute r = 6: A = π(6^2) = 36π.
Final answer: 36π
Question 2
The mean of 5 numbers is 12. If four of the numbers are 10, 11, 12, and 15, what is the fifth number?
A. 10
B. 11
C. 12
D. 13
Step-by-step solution
Mean = (sum of numbers)/(count).
So total sum = 12 × 5 = 60.
Sum of the four known numbers = 10 + 11 + 12 + 15 = 48.
Fifth number = 60 − 48 = 12.
Final answer: 12
Question 3
A line passes through (2, 5) and (6, 13). What is the slope of the line?
A. 1
B. 2
C. 3
D. 4
Step-by-step solution
Slope m = (y2 − y1)/(x2 − x1).
m = (13 − 5)/(6 − 2) = 8/4 = 2.
Final answer: 2
