tenth.
24 in.
17 in.
7 in.

Answer 1

The answer for Surface area is 1160in³ to the nearest tenth

Explanation:

S.A=S.A of big cone + S.A of small cone

S.A=piR²+piRL + pir² +pirl

S.A=22/7×7²+22/7×7×24 + 22/7×7²+22/7×7×17

S.A=22×7+22×24 + 22×7+22×17

S.A=154+528 + 154+374

S.A=628+528

S.A=1156in²

S.A=1160in³ to the nearest tenth
