Problem 1:
What is the area of a circle with radius 5?
Step-by-step: The area of a circle is πr². With r = 5, the area is π(5)² = 25π.
Problem 2:
What is the sum of the interior angles of a triangle?
Step-by-step: The sum of the interior angles of any triangle is always 180°.
Problem 3:
What is the volume of a cube with side length 3?
Step-by-step: The volume of a cube is given by side³. With side = 3, the volume is 3³ = 27.
Problem 4:
What is the perimeter of a rectangle with length 8 and width 3?
Step-by-step: The perimeter of a rectangle is 2(length + width). So, 2(8 + 3) = 2(11) = 22.
Problem 5:
What is the area of a circle with radius 5?
Step-by-step: The area of a circle is given by πr². With radius = 5, the area is π(5)² = 25π.
Problem 6:
What is the surface area of a sphere with radius 4?
Step-by-step: The surface area of a sphere is given by 4πr². With radius = 4, the surface area is 4π(4)² = 4π(16) = 64π.
Problem 7:
What is the volume of a cube with side length 3?
Step-by-step: The volume of a cube is given by s³. With side length = 3, the volume is 3³ = 27.
Problem 8:
What is the perimeter of a rectangle with length 8 and width 3?
Step-by-step: The perimeter of a rectangle is given by 2(length + width). With length = 8 and width = 3, the perimeter is 2(8 + 3) = 2(11) = 22.
