Answer:
<em>The perimeter of the pizza slice is 20.1 cm</em>
Step-by-step explanation:
<u>Perimeter of a Sector of a Circle</u>
The arc length of a sector of a circle of radius r and angle θ is given by:
L = rθ
The angle must be expressed in radians.
The total perimeter of the circular sector, including the two radii, is:
P = rθ + 2r
The pizza slice has a radius of r=7 cm and a central angle of θ=50°
Converting to radians:
The perimeter is:
Calculating:
P = 20.1 cm
The perimeter of the pizza slice is 20.1 cm
For this, we use the given info plus a bit of multiplying and subtraction
part 1)
we know that she's 25 y/m
so 5 minutes simply means 25 × 5
now we simply subtract this from 1000 (the original distance)
part 2)
the total time taken is even easier to find
all we have to do is divide 1000 by 25
