Question

a solid cylinder has radius of base 14 cm and height 15cm. 4 identical cylinders are cut from each base

Answer 1

$= 305 = < < { { {2}^{2} }^{?} }^{?} \times \frac{?}{?}$

Answer 2

Answer:3432

Total surface area=CSA+base area

CSA=CSA of big cylinder+CSA of small cylinder(8)[radius of small cylinder will be 7/2]

Use this we will find CSA=2200

Now base area=2πr^2=2π×14×14=1232

Total=3432
