Answer:
Circumference = 286 cm
Area = 13013/2 cm²
Step-by-step explanation:
Diameter of the Circle = 91 cm
Radius of the circle = 91/2 cm
Area of Circle = πr²
= (22/7) * (91/2)²
= 22/7 * 91/2 * 91/2
= 11 * 13* 91/2 cm² = 13013/2 cm²
Circumference of the circle = 2πr
= 2 * (22/7) * (91/2)
= 22*13 = 286 cm
Hence
Circumference = 286 cm
Area = 13013/2 cm²
