Question 1 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 12. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(12)² = 144π. (Don't confuse with circumference 2πr.)
Question 2 of 10
TEKS ALGEasy
Explanation
Subtract 5 from both sides: 9x = 54. Then divide both sides by 9: x = 6.
Question 3 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 3. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(3)² = 9π. (Don't confuse with circumference 2πr.)
Question 4 of 10
TEKS ALGEasy
Explanation
Subtract 16 from both sides: 4x = 16. Then divide both sides by 4: x = 4.
Question 5 of 10
TEKS ALGEasy
Explanation
Subtract 12 from both sides: 2x = 10. Then divide both sides by 2: x = 5.
Question 6 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 5. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(5)² = 25π. (Don't confuse with circumference 2πr.)
Question 7 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 11. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(11)² = 121π. (Don't confuse with circumference 2πr.)
Question 8 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 7. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(7)² = 49π. (Don't confuse with circumference 2πr.)
Question 9 of 10
TEKS ALGEasy
Explanation
Subtract 10 from both sides: 7x = 84. Then divide both sides by 7: x = 12.
Question 10 of 10
TEKS GEOEasy Diagram
The circle shown has a radius of 6. What is the area of the circle, in terms of π?
Explanation
Area = πr² = π(6)² = 36π. (Don't confuse with circumference 2πr.)
