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 )
The answer is C. 2.
This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to .
, using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.
Now, we reduced the fraction, so all that is left is . This is equal to 2.
So your answer is 2.
I hope this helps :)
