Answer:
The cone has a larger volume.
Step-by-step explanation:
The volume of a cone is given by:
Where:
r: is the radius = 5 cm
: is the height of the cone = 10 cm
Then, the volume of a cone is:
Now, the volume of a pyramid is:
Where:
: is the area of the base
: is the height of the pyramid = 5 cm
The area of the base can be calculated as follows:
Hence, the volume of the pyramid is:
Therefore, the cone has a larger volume.

Answer:
9 m
Step-by-step explanation:
Given that
Width of rectangular flower garden, w = 4 m
Perimeter of rectangular flower garden, p = 26 m
To find:
Length of Lisa's flower garden = ?
Solution:
First of all, let us understand perimeter, length and width of a rectangle.
Let ABCD be a rectangle. Please refer to the attached image.
Opposite sides of a rectangle are equal to each other.
AB = CD = Length
Let the length be m.
BC = DA = Width = 4 m
Perimeter of a closed image is equal to the sum of all the sides of the image.
So, perimeter of ABCD:
Answer:
decrease by 2.16
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
