1. 
- Cone
2. 
- Sphere
3. 
- Cylinder
4. 
- Pyramid
5. 
- Prism
Solution:
1.
Lateral surface area of cone = 
where r is the radius of the cone and l is the slant height of the cone.
2.
Volume of sphere = 
where r is the radius of the sphere.
3.
Total surface area of cylinder = 
where r is the radius of the cylinder and h is the height of the cylinder.
4.
Volume of pyramid = 
where B is the base area of the pyramid and h is the height of the pyramid.
5.
Lateral surface area of prism = 
where p is the perimeter of the base and h is the height of the prism.
Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
Answer:
76 degrees
Step-by-step explanation:
GE = 180 since it is a straight line
GE = GR + FE
180 = 7x+6 +6x-8
Combine like terms
180 = 13x-2
Add 2 to each side
182 = 13x
Divide by 13
182/13 = 13x/13
14 =x
We want FE
FE = 6x-8
FE = 6(14) -8
=84 -8
=76
Answer:
17,28 %
Step-by-step explanation:
81 .............. 100%
14 ....................x%
x = 14×100/81 = 1400/81 ≈ 17,28 %
3x - 7 = 2x - 5<em> add 7 to both sides</em>
3x = 2x + 2 <em>subtract 2x from borh sides</em>
<h3>x = 2</h3>
Check:
L = 3(2) - 7 = 6 - 7 = -1
R = 2(2) - 5 = 4 - 5 = -1
L = R CORRECT! :)
