Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) = 4×pi×r²
our radius r (half the diameter) here is 5m.
=>
As = 4×pi×5² = 4×3.14×25 = 100×3.14 = 314 m²
We want to solve for x
(1/6)/x = 1/2
We multiply both sides by x to get the x in the numerator
1/6 = x*(1/2)
We can divide both sides by 1/2 to get the x alone on the right side
(1/6)/(1/2) = x
When simplified...
x = 1/3
Answer:
<em>0.5 < x < 15.5</em>
Step-by-step explanation:
<u>Triangle Inequality Theorem</u>
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
The two side lengths given in the triangle of the figure are y=8.5, z=8.0, thus the possible values of x lie in the interval
8.5 - 8.0 < x < 8.5 + 8.0
0.5 < x < 15.5
4.5 x 10^-5 is just 0.00045 and 1 x 10^-3 is 0.001
