find the volume of the cone:
1/3 pi r squared × h
1/3 pi (1) squared × 2
= 2/3 Pi (feet cubed)
find the volume of the cylinder:
pi r squared × h
(the radius is 1 foot because its half the diameter which is 2 feet)
pi (1) squared × 2
= 2 Pi (feet cubed)
2 Pi is÷ 2/3 Pi
= 3
therefore it will take 3 cones of liquid to fill a cylinder with a diameter of 2 and height of 2
Answer: it is D and if it is wrong then it doesn’t look like this question was finished.
Step-by-step explanation:
Given:
Net of a triangular prism
To find:
Which equation can be used to calculate the surface area of the triangular prism.
Solution:
Using formulas:
Area of rectangle = length × width
Area of triangle =
Area of left triangle =
Area of right triangle =
Area of bottom = 5 × 10
Area of Middle = 12 × 10
Area of top = 13 × 10
Surface area of triangular prism:
Surface area = Area of left triangle + Area of right triangle + Area of bottom + Area of middle + Area of top
Replace multiplication by brackets.
The equation can be used to calculate surface area of triangular prism is
.
Answer:
336
Step-by-step explanation:
Required Formulas:-
1. Number of ways to select x things out of n things = ⁿCₓ
2. Number of ways to arrange n things when a things and b things are similar = n!/(a!*b!)
Since we have to choose 8 colors and we are having 3 different colors, it is only possible when we select 2 different colors (e.g. 5 red and 3 blue). To find all possible ways we will have to find all unique arrangements of selected color.
Using formula (1), number of ways to select 2 colors out of given 3 colors = ³C₂ = 3
Using formula (2), finding all unique arrangements when 5 stripes are of one color and 3 stripes are of second color = 8!/(3!*5!) = 56
Suppose, we can choose 5 stripes from red color and 3 stripes from blue color or 5 strips from blue color and 3 strips from red color. So there are 2 possibilities of arranging every 2 colors we choose .
∴ Answer=3*56*2 = 336
Answer:
252
Step-by-step explanation:
- 700 mutliply by 12 divided by 100 is equall to 84
- 84multiply by 3
- is equall to 252
