Answer:
V ≈ 571.5 cm³
Step-by-step explanation:
the volume (V) of the solid is calculated as
V = volume of prism - volume of cylinder
volume of prism = area of triangular end × length
= × 11.1 × 10 × 11.8 = 654.9 cm³
volume of cylinder = πr² l ( r is the radius and l the length )
here diameter = 3 cm then r = 0.5 × 3 = 1.5 cm
volume of cylinder = π × 1.5² × 11.8 ≈ 83.41 cm³
then
V = 654.9 - 83.41 = 571.5 cm³ ( to 1 dec. place )

we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
where
a_n----> term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence
