Answer:
Wanda and Dave will catch each other in 54 seconds after Dave starts walking.
Step-by-step explanation:
Let Wanda and Dave catch each other when x be the time after Dave starts walking and y be the distance covered by them
It is given that Wanda started walking along a path 27 seconds before Dave and the constant speed of Wanda is 3 feet per second.
.... (1)
The constant speed of Dave is 4.5 feet per second.
.... (2)
Equate equation (1) and (2).
Divide both sides by 1.5.
Therefore, Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Answer:
Perimeter of the sector = (36 + 8π) cm.
Step-by-step explanation:
Formula to find the of an arc of the circle is,
Length of the arc = 
Here, θ = central angle formed by the arc
r = radius of the circle
Therefore, length of the arc given in the picture = 
= 8π cm
Perimeter of the sector = Sum of all sides of the sector
= Length of radius + length of the arc + length of radius
= 18 + 8π + 18
= (36 + 8π) cm
Perimeter of the sector is (36 + 8π) cm.
