Answer:
The measure of each side of is equal to the corresponding side of when coincides with the other three triangles. The side lengths of the triangle are preserved as the figure rotates.
Answer:
radius = 6 cm
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ← r is the radius
Given V = 288π, then
πr³ = 288π
Multiply both sides by 3 to clear the fraction
4πr³ = 864π ( divide both sides by 4π )
r³ = 216 ( take the cube root of both sides )
r =
= 6
Thus the radius of the sphere is 6 cm
Answer:
5
Step-by-step explanation:
f(x) = 2x - 3x + 7
Plug in 2 every time you see an x within the equation: x = 2
f(2) = 2(2) - 3(2) + 7
f(2) = 4 - 6 + 7
f(2) = -2 + 7
f(2) = 5
