Answer:
As = 2112 cm²
Step-by-step explanation:
given:
A cylinder has a circular base radius 14cm and height of 10cm.
find:
the total surface area of the cylinder. [take pie 22/7] *
solution:
<u>surface area (As) = 2πrh + 2πr²</u>
where r = 14 cm; h = 10 cm; π = 22/7
plugin values into the formula:
As = 2 (22/7) 14 (10) + 2 (22/7) 14²
As = 880 + 1232
As = 2112 cm²
Answer:
ii) curved surface area =2 pie rh
2*22/7*14*21
1548 cm2
iii) total surface area=2 pie r(r+h)
2*22/7*14(14+21)
2780
iv) volume of cylinder=pie r2h
22/7*14*14*21
