we are given
martians =4
plutonians =3
jupiterians=5
so, total number of seats =4+3+5=12
number of seating arrangement for martians is 4!
number of seating arrangement for plutonians is 3!
number of seating arrangement for jupiterians is 5!
total number of seating arrangement is 12!
so, we get
possible seating arrangements are
.............Answer
Answer:
1. The volume of the cylinder is 263 .
2. The volume of the cylinder is 12 .
3. The volume of the cylinder is 3165.1 .
4. The radius of the cylinder is 3.6 cm.
5a. Area of the base is 50.2 .
5b. The curved surface area of the pencil holder is 351.7 .
5c. The surface are of the pencil holder is 452.2 .
Step-by-step explanation:
1. The given shape is a cylinder, so that;
volume of a cylinder = h
= 3.14 x x 5.8
= 262.98128
The volume of the cylinder is 263 .
2. This is also a cylinder, but with a given diameter.
radius =
= = 0.6 m
volume of a cylinder = h
= 3.14 x x 10.6
= 11.98224
The volume of the cylinder is 12 .
3. volume of a cylinder = h
= 3.14 x x 28
= 3165.12
The volume of the cylinder is 3165.1 .
4. volume of a cylinder = h
239 = 3.14 x x 6
239 = 18.84
=
= 12.6858
r =
= 3.5617
The radius of the cylinder is 3.6 cm.
5. Area of the base =
radius =
= = 4 cm
Area of the base = 3.14 x
= 50.24
Area of the base is 50.2 .
5b. Area of the curved surface of the pencil holder = 2rh
= 2 x 3.14 x 4 x 14
= 351.68
The curved surface area of the pencil holder is 351.7 .
5c. Surface area of the pencil holder = 2rh + 2
= 2r(h + r)
= 2 x 3.14 x 4 (14 + 4)
= 452.16
The surface are of the pencil holder is 452.2 .
