0,-8,-7,7,8 there is that correct??????
Answer:
The length of the semicircle arc is 6π
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 12
π = pi
c = π * d
we replace with the known values
c = π * 12
c = 12π
The length of the circumference is 12π
N
ow we divide the circumference by 2 and we will obtain the length of the arc of the semicircle
12π / 2 = 6π
The length of the semicircle arc is 6π
1/5= .2 + 1= 1.2 is 1 1/5 as a decimal
For the first row (the left one), you just need to replace a for 8. If a=8 then a-3 turns into 8-3 and the answer is 5
