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.
