Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = 
πr³
the volume of a hemisphere is half the volume of a sphere, so
V = 
× πr³ = 
πr³ , then
V = π × 3.2³
= π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
Covert into scientific notation?
Answer:
Step-by-step explanation:
Remember the formula:
V= Volume r= radius
Round your answer to the nearest hundredth.
7x^2 + 3
7(4)^2 + 3
7(16) + 3
112 + 3
115.
The answer is A because the input is x and the out put is y so that would make it 9.
