Answer:
This would be a regular polygon.
Step-by-step explanation:
A regular polygon has congruent sides and interior angles.
An irregular polygon does not have congruent sides and all interior angles.
A convex polygon does not have a interior angle greater than 180°.
Lastly, a concave polygon has only one interior angle greater than 180°.
Using the process of elimination, it would not be a convex or concave polygon. Now we have either a regular or irregular polygon. This polygon can not be a irregular polygon because all the sides are congruent. This means that this polygon is a regular polygon!
Answer:
1)
Area
2)
1/2
3)
Radius
Step-by-step explanation:
We know that for any circle with radius r the formula for the area and circumference of the circle is given as:
Area of circle=πr².
and circumference of circle = 2πr.
Hence, to describe the relationship between the area of a circle and its circumference.
The Area of circle is 1/2 times the radius times the circumference.
( Since,
Area=1/2 × r× 2πr
Area=πr² )
Answer:
see explanation
Step-by-step explanation:
Assuming you require to factorise the expressions
16
- 12
+ 4y ← factor out 4y from each term
= 4y(4 - 3y³ + 1)
--------------------------------
64ax² - 49ay² ← factor out a from each term
= a(64x² - 49y²) ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
64x² - 49y²
= (8x)² - (7y)²
= (8x - 7y)(8x + 7y)
then
64ax² - 49ay² = a(8x - 7y)(8x + 7y)
