Answer:
4 1/4
Step-by-step explanation:
2 1/2 + 1 1/4 + 1/2 = 5/2 + 5/4 + 1/2
LCM = 4
5/2 x 2/2 = 10/4
5/4 = 5/4
1/2 x 2/2 = 2/4
10/4 + 5/4 + 2/4 = 17/4
= 4 1/4
Therefore he put 4 1/4 cups altogether.
Answer:
6) B
7) D
Step-by-step explanation:
6)
The surface area of a cylinder is 2 * pi * r * (r + h)
SA = 2 * 3.14 * 3.6 * (3.6 + 8.5) = 2 * 3.14 * 3.6 * 12.1 = 273.6 cm^2
7)
The volume of a cylinder is pi * r^2 * h
V = 3.14 * (3.6)^2 * 8.5 = 345.9 cm^3
Answer:
The Number sentence 36 ÷ 3 will be used to find number of guest invited in Ryan dinner.
There were 12 guests invited to Ryan's dinner.
Step-by-step explanation:
Given:
Total Number of pieces = 36 pieces.
Also Given:
Ryan set a table with a fork, knife, and spoon for each dinner guest.
From above we can conclude that;
Number of Piece for each Dinner guest = 3 piece.
We need to find the number of guest invited in Ryan dinner.
number of guest invited in Ryan dinner will be equal to Total Number of pieces used for guest divided by Number of Piece for each Dinner guest.
framing in equation form we get;
number of guest invited in Ryan dinner = 
Hence The Number sentence 36 ÷ 3 will be used to find number of guest invited in Ryan dinner.
Also There were 12 guests invited to Ryan's dinner.
Answer:
446.75 y^2
Step-by-step explanation:
First, Kelly found the area of a circle, not half a circle, which is on top of the figure. She also shouldn't have subtracted the area of the circle by the airea of the base, as she is trying to find the area of the ENTIRE figure.
.5 TIMES pi times 9^2 = 122.75
the second part, calculating the square base is correct..
122.75+324 = 446.75 y^2
