Answer:
Step-by-step explanation:
144.44 in² is the closest amount of paper she will use to wrap the gift.
Solution:
The given net is the shape of the cylinder.
Diameter of the circle = 4 in
Radius of the circle = 4 ÷ 2 = 2 in
Width of the container = 10.5 in
Length of the container is same as the circumference of the circle.
Area of the circle = 
= 
= 12.56 in²
Area of the 2 circles = 2 × 12.56 = 25.12 in²
Area of the rectangle = circumference × height
= 
= 
= 131.88 in²
Area of the net of the container
= Area of the circles + Area of the rectangle
= 12.56 in² + 131.88 in²
= 144.44 in²
Area of the net of the container = 144.44 in²
Hence 144.44 in² is the closest amount of paper she will use to wrap the gift.
4. is correct
5. A is correct
6. B is correct
(3n-2m) (3n-2m)
(you multiply the first number (3n) by the first number in the 2nd bracket (3n) and then by the second number in the 2nd bracket (-2m)), and you do the same for -2m
9n2 - 6mn -6nm +4m2
9n2 -12mn + 4m2
Answer:
<u>2772 in³</u>
Step-by-step explanation:
- Volume = πr²h
- V = 22/7 x 7 x 7 x 18
- V = 22 x 7 x 18
- V = 154 x 18
- V = <u>2772 in³</u>
