Step-by-step explanation:
d=2r
πr^2
10/2=r
5=r
5^2π
25π=78.5398
Hope that helps :)
Fifth term / second term = a1r^4 / a1r = r^3 = 768 / -12 = -64
so r = -4 and first term a1 = -12/-4 = 3
answer is 3*(-4)^(n-1)
Its C
Answer:
x = 1/25 = 0.040
x = 10
x = 0
b = 0
Step-by-step explanation:
List the coordinates,
Coordinates are shown as (x,y)
If 2+2+7+7 is 16
You make those your side lengths
Coordinates are (9,7) (2,7) (2,5) (9,5)
they maybe slightly off because of the broken peice of paper
