C= πd+2l
C= π*62+2*100
C= 194.99+200
C= 394.99 m²
I don't know why it doesn't match up with the choices, but this is the correct answer. So when putting the answer in, put 394.68 since it's the closest answer chice
The area is 81*pi-162. Look at the triangle formed by the chord and the two radii connected to the endpoints of the chord. Since 18^2+18^2=(18*\sqrt2)^2, this is an isosceles right triangle by Pythagorean theorem. The area of the quarter circle containing the region we look for is pi*18^2/4=81*pi. The area of the right triangle is 18*18/2=162. The difference between these two areas, or 81*pi-162, is the area of the smaller region.
Answer:
a. x/3.
Step-by-step explanation:
You divide to find a quotient so it is x / 3.
Answer:
10 lbs
Step-by-step explanation:
Let c represent the number of pounds of cashews to be added. Then the total cost of the mix will be ...
4.00c +1.5(40) = 2.00(c+40)
4c +60 = 2c +80 . . . . . . . . . . . simplify
2c = 20 . . . . . . . . . . . . . . . . . . . subtract 60 + 2c
c = 10 . . . . . . . . . . . . . . . . . . . . .divide by 2
10 pounds of cashews should be mixed with the peanuts.
