Answer:
the formula is (n-2)180 degrees
so its 7020
Well (1.57- 0.6 X 0.6) x 0.3 = 0.363
Circumference=2πr
2π=2πr
r=1
area=πr^2
area=π(1)^2
area=π
Answer:
because they made a mistake
Answer:
11,8,5
Step-by-step explanation:
an=11-3(n-1)
Let n=1
a1 = 11 - 3(1-1)
= 11 -0
=11
Let n=2
a2 = 11-3(2-1)
= 11 -3(1)
= 8
Let n=3
a3 = 11-3(3-1)
= 11 -3(2)
= 11 -6
=5
