We must find the radius so we can plug this into the formula for surface area.
Circumference =
We are going to plug this in as our radius for the most accurate answer.
The surface area of a sphere is
Surface Area =
≈ 451.93 units
Hmmm well may I ask what your doing with the shapes bc um well if you put them shapes in the circle/oval why is it hard? I don’t do this stuff I’m confused...
Answer:
20% alcohol = 1 gal
10% alcohol = 9 gal
Step-by-step explanation:
Let
x = 20% alcohol
y = 10% alcohol
x + y = 10 (1)
0.20x + 0.10y = 10*0.11
0.20x + 0.10y = 1.1 (2)
From (1)
x = 10 - y
Substitute x = 10 - y into (2)
0.20x + 0.10y = 1.1
0.20(10 - y) + 0.10y = 1.1
2 - 0.20y + 0.10y = 1.1
- 0.20y + 0.10y = 1.1 - 2
-0.10y = -0.9
y = -0.9/-0.10
y = 9 gal
substitute y = 9 into (1)
x + y = 10
x + 9 = 10
x = 10 - 9
x = 1 gal
20% alcohol = 1 gal
10% alcohol = 9 gal
Answer:
Step-by-step explanation:
960 which is the area u divide by the one foot which is 144 square units to get your answer,6.66666666667
-10 and 2
-10 x 2 = -20
-10 + 2 = -8
