Answer:
The perimeter of a circle is π × d. Here's is the diameter of the circle. Hence, the perimeter of a circle is half of that of the circle that is ½ π × d.
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Step-by-step explanation:
B² - 4ac
= 8² - 4*(-2)*(-9)
= 64 - 72
= -8
Answer: hiiiii
Step-by-step explanation:
Answer:
A) 5 and B) 5
Step-by-step explanation:
A) 5x-12=13
+12 +12 (add 12 to the 13)
5x=25
(then divide 25 by 5 which is 5 so the answer is 5)
B) 8(x+3)=64 (first use distributive property)
8x+24=64
-24 -24 (then subtract 24 to 64 which is 40)
8x=40
(then divide 40 by 8 which is 5 so that is it!)
I believe this is correct, I hope this helps :D
