Answer:
circumference=9.42
Step-by-step explanation:
the formula for circumference is pi x diameter.
Answer:
100 if rounded to hundreds
140 if rounded to tens
Step-by-step explanation:
A rectangle is a quadrilateral with either two opposite sides equal and parallel to each other. That is AB is parallel and equal to CD and AD parallel and equal to BC. Parallel lines have equal slopes.
Thus, AB slope is 2, while that of CD is also 2, therefore they are parallel to each other. In addition the modulus of AB and that of CD is the same thus they are equal in length.
AD slope is -1/2 while that of BC is also -1/2 therefore the two are parallel to each other. In addition they are equal in length therefore they are equal in length.
Moreover AB is perpendicular to BC and AD (product of slope of two perpendicular lines is -1)
Therefore, it can be concluded that Quadrilateral ABCD is a rectangle.
Answer:
x is equal to 106
Step-by-step explanation:
when x is on the opposite side of 2 intersecting lines, it will be the same angle as the angle opposite to it
You should do 24.30/9 which equals $2.70
