What is the volume of 32 metre high cylindrical tank? I. The area of its base is 154 m2. II. The diameter of the base is 14 m.
Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
Given, height = 32 m. I. gives, area of the base $=154 \mathrm{m}^{2}$. $\therefore$ Volume $=(\text{area of the base} \times \text{height})=(154 \times 32) \mathrm{m}^{3}=4928 \mathrm{m}^{3}$. Thus, I alone gives the answer. II. gives, radius of the base $=7 \mathrm{m}$. $\therefore$ Volume $=\pi r^{2} h=\left(\frac{22}{7} \times 7 \times 7 \times 32\right) \mathrm{m}^{3}=4928 \mathrm{m}^{3}$. Thus, II alone gives the answer. $\therefore$ Correct answer is (c).
