    A 128m Correct Answer Incorrect Answer
    B 121m Correct Answer Incorrect Answer
    C 110m Correct Answer Incorrect Answer
    D 142m Correct Answer Incorrect Answer

    Solution

    Πr2 =154 22/7×r2=154 R = 7cm And now volume of the conical tent =1232 1/3πr2 h=1232 1/3 ×22/7 ×49 ×h = 1232 h= (1232×7×3)/22×49=24m l = √ 576+49 = √ 625 =25cm Area of the canvas required to build the tent = π r l Which will equal to the area of the rectangular canvas. π r l = 2×length of canvas 22/7× 7×25 = 5 × length of canvas length of canvas =22×5 = 110m
