Question

please tell me this question.ans-4.146cm².​

Answer 1

Answer:

3850 cubic cm

1408 square cm

Step-by-step explanation:

$volume = \pi {r}^{2} h \\ = \frac{22}{7} \times 7 \times 7 \times 25 \\ \\ = 22 \times 7 \times25 \\ \\ = 3850 \: {cm}^{3}$

WHOLE SURFACE AREA=

$(2\pi \times r \times h )+ (2\pi {r}^{2}) \\ \\ = 2 \times \frac{22}{7} \times 7 \times 25 \: \: + \: \: 2 \times \frac{22}{7} \times 7 \times 7\\ \\ = 44 \times 25 + 44 \times 7 \\ \\ = 1100 + 308 \\ = 1408 \: {cm}^{2}$
