Answer: 121 cm² Step-by-step explanation: radius of circle= 7cm then, Circumference of circle= 2πr circumference = 2×22×7/7 circumference = 2×22= 44 cm perimeter of square = 4 × side 44 = 4 × side side = 44/4 = 11 cm area of square = side × side area of square = 11 × 11 = 121 cm² Reply
Answer:
121 cm²
Step-by-step explanation:
radius of circle= 7cm
then, Circumference of circle= 2πr
circumference = 2×22×7/7
circumference = 2×22= 44 cm
perimeter of square = 4 × side
44 = 4 × side
side = 44/4 = 11 cm
area of square = side × side
area of square = 11 × 11 = 121 cm²
