Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
ooh, funzo
must equal 10 cups
trail mix is just a mix of nuts and salty and sweet things to give you energy. there is no absolute recepie that you have to follow
you could literally just have 2 cups cashews, 2 cups cherries, 2 cups sunlower seets, 2 cups M&M's, 2 cups granola (and 2 cups=6 of the 1/3 cup measure or 8 o the 1/4 cup measure), but I don't think that's what your teacher wants
let's make a realistic recipie
(I don't like cherries in my trail mix so let's ust put the minimum amount, 1/4 cup)
1/4 cup cherries
2+3/4+2/3=2 and 17/12=3 and 5/12 cup cashews
1 and 1/3 cup sunower seets
2 cups granola (use 8 of the 1/4 cup or 6 of the 1/3 cup scoop)
3 cups M&M's (use 12 of the 1/4 cup or 9 of the 1/3 cup scoop)
there's a good recipee
Answer:
x = 3.5
Step-by-step explanation:
diameter = radius × radius
d= ( 3x + 1 ) + ( x + 8 )
3x + 1 = x + 8
subtract 1 and x
2x = 7
divide by 2
x = 3.5
