As per the inquiry,
We get the figure given underneath,
We realize that,
Complete surface space of shape framed = Curved space of first cone + Curved surface space of second cone
Since, the two cones are indistinguishable,
We have,
All out surface space of shape framed = Curved space of first cone + Curved surface space of the subsequent cone
= 2(Surface space of cone)
We additionally realize that,
Surface space of cone = πrl, where r = range and l = incline stature
What’s more, the absolute Surface space of shape so framed = 2πrl
Given in the inquiry that,
Range, r = 8 cm
Tallness, h = 15 cm
Consequently,
Region = Curved space of first cone + Curved surface space of the subsequent cone
= 2 (Surface space of the cone)
\[=\text{ }2\text{ }\times \text{ }\pi rl\]
\[=\text{ }2\text{ }\times \text{ }\pi \text{ }\times \text{ }r\text{ }\times \text{ }\surd \left( r2\text{ }+\text{ }h2 \right)\]
\[=\text{ }2\text{ }\times \text{ }\left( 22/7 \right)\text{ }\times \text{ }8\text{ }\times \text{ }\surd \left( 82\text{ }+\text{ }152 \right)\]
\[=\text{ }50.28\text{ }\times \text{ }\surd 289\]
= 854.85 cm2
= 855 cm2 (approx)
Consequently, the surface space of shape so framed is 855cm2.
