Answer:

65 1/3 or 196/3

Step-by-step explanation:

9 1/3 can be written as 28/3 (9 times 3 plus 1)

28/3 times 7/1 (because any whole number can have a 1 as the denominator)

Multiply top to top and bottom to bottom

28 times 7/ 3 times 1

196/3

Simplify to

65 1/3 but 196/3 will work out as well

A running track consists of two parallel lines that are connected at each end but the curved boundary of a semicircle. The paral

saveliy_v [14]

Answer:

The area inside the running track is 248.5 m².

Step-by-step explanation:

The area inside the running track is given by the sum of the area of a rectangle and the area of a semicircle:

$A_{t} = A_{r} + 2A_{c}$

$A_{t} = x*(2r) + 2*(\frac{\pi r^{2}}{2})$

Where:

x: is one side of the rectangle = 30 m

r: is the radius = half of the other side of the rectangle = 7/2 m = 3.5 m

Hence, the total area is:

$A_{t} = 30*7 + \pi (3.5)^{2} = 248.5 m^{2}$

Therefore, the area inside the running track is 248.5 m².

I hope it helps you!
