Step-by-step explanation:

perimeter = 2 × 22/7 × r ( 22/7 = π )

176 = 2 × 22/7 × r

176 × 7/2 × 22 = r

28 cm = radius

Area = πr²

= 22 × 7 × ( 28 ) ²

= 22 / 7 × 784

= 2464 cm²

Answer:

Step-by-step explanation:

perimeter=circumference=2πr

176=2 x 22/7 x r

(176x7)/44 = r

28 = r or r=28

area of circle= πr²

                     = 22/7 x 28²  

                      = 2463.01 cm²
