Use the equation for the volume of a cone to solve for the height:
Answer:
- Length = 28 meters
- Width = 4 meters
Step-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters
Answer:
i dont know
Step-by-step explanation:
Answer:
it takes 2/3 gallons to paint each square yard of wall.
You know that Tyler painted 9/2 square yards area with 3 gallons of paint and want to know many gallons of paint does it take to paint each square yard of wall.
Then 9/2 square yards - 3 gallons
1 square yards - x gallons,
mathematically this is proportion: (in the picture)
Answer: 4,772.8 cm2
Step-by-step explanation:
Hi, to answer this question we have to calculate measures of the rectangular label:
The width of the label is equal to the height of the can (8 cm), and the length is equal to the perimeter of the top or bottom of the can.
Perimeter of a circle (circumference): 2 π radius
Replacing with the values given:
C = 2 (3.14) 5 = 31.4 cm
So, the area of one label is:
Area of a rectangle: length x width = 31.4 x 8 = 251.2 cm2
Multiplying for the number of labels (19)
251.2 x 19 = 4,772.8 cm2
