What are we suppose to evaluate
Answer:
<u>Given</u>
a.
<u>Volume of the half-sphere:</u>
- V/2 = 1/2*4/3*πr³ = 2/3*3.14*1.6³ = 8.6 cm³ (rounded)
b.
<u>Volume of the cylinder:</u>
- V = πr²h = 3.14*1.6²*6.2 = 49.8 cm³
c.
<u>Volume of the figure:</u>
- V = 8.6 + 49.8 = 58.4 cm³
Answer:
30 ft
Step-by-step explanation:
The first rectangle is 4 x 2 = 8
The second rectangle we can find the missing side length by subtracting the four by two and add two to the second rectangle. 6 x 2 = 12
The last rectangle is 5 x 2 = 10
8 + 12 + 10 = 30
Answer:
Step-by-step explanation:
we know that
The area of a sector is equal to
where
------> is the angle in degrees
r is the radius of the circle
In this problem we have
assume
substitute the values
