What is the sector area created by the hands of a clock with a radius of 9 inches when the time is 4: 00? 6.75π in.2 20.25π in.2 27π in.2 81π in.2?

we know that

The area of a circle is equal to

where

r is the radius of the circle

In this problem we have

substitute in the formula

The area of the complete circle subtends

When the time is 4:00 the angle formed by the hands of a clock is

so by proportion

Find the area of the sector area

therefore

the answer is the option

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
