the answers for the Circumference and Area of circles quick check and practice, for connexus, i need them ASAP
1. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
2. The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
Quick Check:
1. What is the circumference of a circle with a radius of 5 cm?
- C = 2π(5) = 10π cm
2. What is the area of a circle with a radius of 6 inches?
- A = π(6)^2 = 36π square inches
Practice:
1. Find the circumference of a circle with a radius of 8 cm.
- C = 2π(8) = 16π cm
2. Find the area of a circle with a radius of 3.5 meters.
- A = π(3.5)^2 = 12.25π square meters
