Answer:
C=2 x pi x r
11pi=2pi x r
11pi/2pi=2pi/2pi x r
r=11/2
A= pi x r^2
A= pi x (11/2)^2
A=121/4pi inches^2
Step-by-step explanation:
Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
Answer:
<1 and <2 are alternate exterior angles
<3 and <4 are consecutive interior angles
Step-by-step explanation:
<1 and <2 are alternate exterior angles
Alternate exterior angles are on opposite outside of the lines
<3 and <4 are consecutive interior angles
Consecutive interior angles are on the same side on the inside of the line
