Answer:
Area for Triangle is: 1/2bh or bh/2
Area for Trapezoid (As shown in picture):
1/2h(b1+b2)
You’d have to do 1/2 x 18(15+37) for the quesyion in the picture
Hope this helped!

Step-by-step explanation:
you need to find how much food is used for 1 person then times that answer by 100 to find how much food is needed
Almons:walnuts:rasins=1:2:3
x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute
12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins
1/3 pound walnuts
2/3 pound almonds
1 pound rasins
Answer:

Step-by-step explanation:
given,
radius of sphere = 3
volume of cone:

r is the radius of circular base
h is the height of the cone
here r = x and h = 3 + y
now, volume in term of x and y

Applying Pythagoras theorem
x² + y² = 3²



differentiating both side

for maxima 

y² + 2 y - 3 = 0
(y+3)(y-1)=0
y = 1,-3
y cannot be negative so, volume at y = 1


Hence, the largest cone which can be inscribed in the spheres of the radius 3 has volume
