Answer: 784π mm²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle which is shown below.
Area = πr²
Notice that here, we're given the diameter instead of the radius.
Remember that the radius is equal to half of the diameter. So the radius of this circle will be equal to half 56 millimeters or 28 millimeters.
So plugging into the formula, we have (π)(28 mm)².
A common mistake is to plug 56 millimeters into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (28 mm)² is equal to (28 mm)(28 mm) or 784 mm².
So we have 784π mm².
So the area of the circle is 784π mm².
Answer:
x=1, y=2.5
Step-by-step explanation:
Width = 9cm
Length = 18cm
<u>Explanation:</u>
Let width = b,
So, length = 2b
Perimeter of rectangle = 2x(length + width)
According to the question,
Hence,
Width = 9cm
Length = 18cm
Answer:
(x, y ) → (x - 6, y - 2 )
Step-by-step explanation:
Given
P(- 10, 1 ) → P'(- 16, - 1 )
Note that the x- coordinate of the image is 6 less than the original and
The y- coordinate of the image is 2 less than the original, thus
(x, y ) → (x - 6, y - 2 )
