Answer»

Step-by-step EXPLANATION:

radius = 35cm \\ \\ circumference = 2\pi \times r \\ = 2 \times \frac{22}{7} \times 35 \\ = 2 \times 22 \times 5 \\ = 220 \: {cm}^{2} \\ \\ \\ area \: \: = \pi {r}^{2} \\ = \frac{22}{7} \times {35}^{2} \\ = \frac{22}{7} \times 35 \times 35 \\ = 22 \times 5 \times 35 \\ = 3850 \: {cm}^{2}
