alleryଏକ ପତଳା ସିଲିଣ୍ଡରାକାର ଖୋଳର ଘନଫଳ କାହା ସହିତ ସମାନ?
A2π × ଅନ୍ତଃ ବ୍ୟାସାର୍ଦ୍ଧ × ଉଚ୍ଚତା × ମୋଟେଇ
B2π × ମାଧ୍ୟ ବ୍ୟାସାର୍ଦ୍ଧ × ଉଚ୍ଚତା × ମୋଟେଇ
C4π × ମାଧ୍ୟ ବ୍ୟାସାର୍ଦ୍ଧ × ଉଚ୍ଚତା × ମୋଟେଇ
Dπ × ମାଧ୍ୟ ବ୍ୟାସାର୍ଦ୍ଧ² × ଉଚ୍ଚତା × ମୋଟେଇ
Answer & Solution
Correct answer: B. 2π × ମାଧ୍ୟ ବ୍ୟାସାର୍ଦ୍ଧ × ଉଚ୍ଚତା × ମୋଟେଇ
ଖୋଳଟିକୁ ଖୋଲିଦେଲେ ଏହା ହାରାହାରି ବ୍ୟାସାର୍ଦ୍ଧର 2 pi ଗୁଣ ଲମ୍ବ ବିଶିଷ୍ଟ ଏକ ପତଳା ସ୍ଲାବ୍ ପ୍ରଦାନ କରେ, ଯାହାର ପ୍ରଦତ୍ତ ଉଚ୍ଚତା ଏବଂ ମୋଟେଇ ଥାଏ।
