Answer:

Step-by-step explanation:
Given
See attachment for ABCD
--- the scale factor
Required
The coordinates of A'
From the attachment, we have:

So:



So, the area of a parallelogram is the base times the height or

a being area
b being base
h being height
the height is 8 cm and the base is 15 cm
(remember: the heght should be perpendicular to the base)
so we plug in 8 for h and 15 for b to get

and 15 × 8 = (10 × 8) + (5 × 8) = 80 + 40 =120
So the answer is 120

Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286
