Answer:
diameter Circle = 70
Area Circle =22/7.35.35 = 3850
Area circle + Area Square = 5450
Area Square =5450 -3850 = 1600
side Square = square root (1600) =40
Circum Square = 4.40=160
Circum Circle =22/7.70=220

Answer:
Step-by-step explanation:
From the question,
πr² + s² = 5450
22 x 35 x 35/7 + s² = 5450
22 x 5 x 35 + s² = 5450
3850 + s² = 5450
s² = 1600
s = 40 cm
2πr + 4s = 2 x 22 x 35/7 + 4 x 40
= 220 + 160
= 380 cm
