The formula for area of a sector is...

A = \frac{1}{2} r^{2}θ

NOTE θ is converted from degree to radian

θ = 167 × \frac{\pi }{180}

θ = \frac{167\pi }{180}

so...

A = \frac{1}{2}(17.8)^{2} (\frac{167\pi }{180})

A = (1/2)(316.84)(2.9146)

A = 158.42 * 2.9146

A = 461.7

Hope this helped!

Bob had 18 crackers Sam eat 1/6 of the crackers and sue ate 1/3 of the crackers. how many crackers did Bob have left
Lapatulllka [165]
We can add 1/6 & 1/3 together to find out the total amount of crackers that were eaten:

1/6 + 1/3   (Find the Common Denominator. In this case it is 6.) 
= 1/6 + 2/6
= 3/6 (Now find the Lowest Terms. Both 6 & 3 divide into 3)
= 1/2 (In Lowest Terms)

This means that 1/2 of the Crackers have been eaten.

1/2 of 18 = 9 

Therefore, Bob has 9 Crackers left.
