9ft n 3 inches , because 12 inches is a feet ! if you know then you know
Two solids are said to be similar when their corresponding sides and angles are proportional and congruent. Since the solids here are similar, we calculate as follows:
Assuming the solid is a sphere
V1/V2 = r1^3 / r2^3 = 1331/216 = 6.16203
r1/r2 = 11/6
A1/A2 = (r1/r2)^2
324/A2 = (11/6)^2
A2 = 42.84 m^2

Rationalize.

This can be further simplified to the decimal:
-0.43006...
I hope this helps :)
