Step-by-step explanation:
The center of dilation is a fixed point on a plane. It is the starting point from which we measure distances in a dilation
What you are asking is x + 30 ÷ 11 = 1
x + 30 ÷ 11 = 1
Simplify
x + 30/11 = 1
Subtract 30/11 from each side
x + 30/11 - 30/11 = 1 - 30/11
x = -19/11
Answer:
3139.5 m²
Step-by-step explanation:
the formula for the volume of a sphere of radius r is V = (4/3)πr³. In this particular case, V = 2098π m³ = (4/3)πr³, and from this we can calculate the radius, r:
2098π m³
r³ = ----------------- = (3/4)(2098 = 1483/5
(4/3)π
Thus r = ∛1573.5 m³ = 11.64 m
Then the surface area is A = 4πr², which in this case is
A = 4(3.14159)(11.64 m)^2 = 1702.6 m² (which is to the nearest tenth).
