The slant height of a bucket is 45 cm and the radii of its top and bottom are 28 cm and 7 cm respectively. The curved surface area of the bucket is
(a) 4953 cm2 (b) 4952 cm2 (c) 4951 cm2 (d) 4950 cm2
(d) 4950 cm2 correct option.
Slant Height (L) = 45 cm
Radius of the top of the bucket (R) = 28 cm
Radius of the bottom of the bucket (r) = 7 cm
CSA of the bucket = πL(R+r)=227×45(28+7)=227×45×35
