For a circle of radius 7 feet, find the length of an arc s with a measure of 26°. s = 7/180 π feet
s = 91/180 π feet
s = 182 π feet
s = 91/90 π feet

Step-by-step explanation:

r = 7 ft

θ =  (26/180)π = (13/90)π radians

arc length = rθ = 7×(13/90)π = (91/90)π ft

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
