Solve proportion. Thanks!

r= -1/4

Step-by-step explanation:

to solve this, you would need to cross multiply, so:

10(r+1)=2(r+4)

then, you would have to use the distributive property to simplify each side of the equation:

10r+10= 2r+8

now, subtract 8 from both sides to isolate the variable on one side:

10r+2=2r

Now, subtract 10r from both sides to combine like terms:

2= -8r

now divide by -8 on both side, and simplify:

-2/8=r

-1/4=r

so, r= -1/4

hope this helped :D im sorry if its hard to understand T.T

picture below

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
