Option (3)
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
=
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
= 1207.6 m
Option (3) will be the correct option.
1)<span>960 square feet
</span>2) B. 25 cm ^2
The area of a regular pentagon can be found using the formula.
s=side length
A≈960 square feet
The apothem of a square is half of the side length. 2.5*2=5. 5^2 = 25cm^2
