2.5 hours. You take the total amount of kilometers and divide it by the kph (kilometers per hour), which in this case is 11. If you do that, you'll get your answer of 2.5 hours or 2 hours and 30 minutes.

Use function notation to represent the area of a circle whose circumference is 103 cm

Nataly_w [17]

Circumference of the circle $=103$ cm

i.e., $C = 2 \pi r = 103$

i.e., $r = \frac{103}{2 \pi}$

Area of the circle is given by

$A = \pi r^2$

$A = \pi (\frac{103}{2 \pi})^2$

$A = \pi (\frac{10609}{4 \pi^2})$

$A =\frac{10609}{4 \pi}$

Therefore, the area of the circle is: $A =\frac{10609}{4 \pi}$ $cm^2$

Based only on the given information, it is guaranteed that AD = CD.

pickupchik [31]

Answer:

Not really, actually it depends on the shape given whether it's a rectangle, a square etc. Because you can't conclude that the shape of a rectangle with such dimensions could be guaranteed.
