Answer:
16pi cm^2, 112pi cm^3, 351.68 cm^3
Step-by-step explanation:
Given: Height=7cm, radius=4cm
1. The base is a circle and Area of circle = pi * r^2
Plug in the radius to get --> A = pi * (4cm)^2 = 16*pi cm^2
2. This is asking for the volume of the cylinder.
Volume of cylinder is V=h*pi*r^2 --> 7cm * pi * (4cm)^2 = 112 pi cm^3
3. Just plug 3.14 into pi --> 112 * pi cm^3 = 351.68 cm^3
Answer:
4 gallons
Step-by-step explanation:
2/3 divided by 1/6 Don't cancel me if wrong
Answer:
i think -12,9 and you multiply it by x,-2
If it gained 4 million people every 6 years, then the gain PER year would be 1.5 million. from 1992 to 2012 is 10 years. So, 1.5 times 10 is 15. 72 + 15 =87.
Your answer is 87 million.
Answer:
The answer is
<h2>134 ft³</h2>
Step-by-step explanation:
Volume of a hemisphere is given by
where
r is the radius of the hemisphere
From the question
diameter = 8 ft
radius = 8/2 = 4 ft
Substitute the value into the above formula and solve
We have the final answer as
<h3>134.0 ft³ to the nearest tenth</h3>
