Lily200:
i think the answer is wrong!!!
yup the ans. it's really wrong
can u tell me what's the right answer
yup
yes
ok than tell me
T.s.a=2pi r (r+h)
=2×3.14×10 (10cm+14cm)
=1507.2 cm^2
It is open at the top
Therefore area =1507.2 - pi r^2
=1507.2 - 3.14 × 10^2
=1507.2 - 314 cm^2
=1193.2 cm^2
=2×3.14×10 (10cm+14cm)
=1507.2 cm^2
It is open at the top
Therefore area =1507.2 - pi r^2
=1507.2 - 3.14 × 10^2
=1507.2 - 314 cm^2
=1193.2 cm^2

Answer:
Step-by-step explanation:
hey buddy,
area of cylinder = 2 pi r (r + h)
= 2 pi 10 ( 10 + 14 ) ---------------- take pi = 3.14
= 1507.2
top is open
therefore area= 1507.2 - pi r^2
= 1507.2 - 3.14 x 10^2
= 1507.2 - 314
=1193.2 cm^2
hope it helps!!!
if possible make brainliest plzz!!!
