Answer:
With a circle with radius 7 cm, the circumference of given circle is 14π (cm) and the area is 49π (cm²).
Explanation:
Given: radius = 7 cm
Circumference of a circle: C = 2πr
C = 2πr
Substitute given value radius.
C = 2π(7)
Multiply 7 and 2.
C = 14π cm.
Area of a circle: A = πr²
A = πr²
Substitute given value radius.
A = π(7)²
Square the 7.
A = 49π cm²
