Length of arc=4π

Step-by-step explanation:

Length of arc=¤/360 x 2xπxr

Where:

¤=72

r=10

Length of arc=72/360 x 2xπx10

Length of arc=0.2 x 20π

Length of arc=4π

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
