How can I find the angular position in radians of the minute hand of a clock at 5:00, 7:15, an 3:35?

A) 5:00 
<span>At 00 minutes, the minute hand is point straight up. That is one quarter turn of the entire circle. One-fourth of 2π radians is 1/2 π, or π/2 </span>

b) 7:15 
At 15 minutes, the minute hand is pointing straight to the right, along the imaginary positive x-axis, so it has turned through none of the circle. 0 radians.

c) 3:30 
<span>This one isn't as clean as the others. Let's first find the 35 minute position: it occurs at hour number 7. Identify that measuring from 3 (positive x-axis, measuring counter clockwise) you have to turn through 40 minutes worth of clock. 40 minutes represents 40/60 of an entire clock, which reduces to 2/3. 2/3 of all the radians in a circle (2π of them) is 4/3π, or 4π/3. 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!
Blababa [14]

For this case we have that by definition, the circumference of a circle is given by:

C = \pi * d

Where:

d: It is the diameter of the circle

They tell us that:

d = \frac {35} {2}\\\pi = \frac {22} {7}

Substituting:

C = \frac {22} {7} * \frac {35} {2}\\C = \frac {770} {14}\\C = 55 \ cm

Thus, the circumference of the circle is 55 centimeters.

Option B

After losing 22 lb in each of the first two
Pavel [41]

Answer:

Weight on 1 may = 104 lb

Step-by-step explanation:

Given:

Weight on last may = 110 lb

Weight gain for to week = 2 x 19 = 38 lb

Weight lose for to week = 2 x 22 = 44 lb

Find:

Weight on 1 may

Computation:

Weight on 1 may = Weight on last may - Weight gain for to week + Weight lose for to week

Weight on 1 may = 110 - 44 + 38

Weight on 1 may = 104 lb
