Answer:
To find the original dimensions, write a proportion with the scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve. To find new dimensions, write a proportion with the new scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve.
Answer: B
Step-by-step explanation:
Answer:
pi
Step-by-step explanation:
First find the circumference of a circle with radius 4
C = 2 * pi *r
C = 2*pi*4
C = 8pi
A circle has 360 degrees
Find the fraction of a circle that 45 degrees is
45/360 = 1/8
Multiply the fraction by the circumference
1/8 *8pi = pi
B.

c. the sum of adjacent angles of parallelogram is 180 degrees
d. Subtraction property
Its already a integer number
