area = pi * r^2
here, the radius is 2 as its the diameter/2.
so the area is 4pi.
circumference = 2*pi*r.
so the circumference is 4pi as well.
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)
Hope this helps :)
First question: 1st and 3rd expression are the answer.
2nd question: I'm not sure
3rd question: (2p+9)^2
1st condition: 2 pairs of congruent adjacent sides: it's either the square or rhombus
2nd condition: adjacent &congruent Angles : Square:
Then only the square satisfies the request of the problem (A solution)
