Your answer is C. 13.3 in. You take your circumference, and divide it by 3.14, which gives you your diameter. Then you divide that by 2 for the radius.

83.524/3.14=26.6
26.6/2=13.3

Answer: 13.3

The olympic record for the marathon is 2 h, 9 min, 21 s. the marathon distance is 26 mi, 385 yd. determine the average speed (in
Vika [28.1K]
The average speed of an object moving is its rate of change per time interval. It is equal to the total distance traveled divided by the total time it takes to travel that distance. We calculate the average speed of the olympic record as follows:

The units of the average speed should be miles per hour so we need to convert the distances in to miles and time into units of hours.
distance 1= <span>26 mi
distance 2 = 385 yd ( 1 mile / 1760 yd ) = 0.21875 mi
total distance = 26 + 0.21875 = 26.21875 mi

time 1 = 2 h
time 2 = 9 min ( 1 h / 60 min ) = 0.15 h
time 3 = 21 s ( 1 h / 3600 s ) = 0.0058 h
total time = 2 + 0.15 + 0.0058 = 2.1558 h

average speed = total distance / total time = 26.21875 mi / 2.1558 hr = 12.1620 mi / h</span>

City park is a right triangle with a base of 49 yrds and a height of 25 yard in a map The park is a basic 3 inches and the heigh
ASHA 777 [7]

Answer:

3/49

Step-by-step explanation:

The area of a rectangle is found using A = l*w. At the park, it measures A = 49*25 = 1,225 yards².

On the map the area is A = 3*25 = 75 inches².

The ratio of the area of the map to the area of the park is found by placing 75 ovre 1,225. Then simplify if possible.

\frac{75}{1225} = \frac{3*25}{49*25} = \frac{3}{49}
