r=0.25 miles
l=2×
=0.5 × 3.14
=1.57
120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:
(To nearest tenth)
Answer:
or approximately
units
Step-by-step explanation:
The formula for finding the circumference of a circle is , where
= circumference and
= radius. In this case,
, so after plugging that into
, we get:
Since is approximately
,
, which rounds to
. Therefore, the circumference of the circle is
, or approximately
units. Hope this helps!
