Answer:
433.5 in²
Step-by-step explanation:
A cube has 6 sides
Area of 1 side = 8.5 x 8.5 = 72.25 in²
Area of 6 sides = 72.25 x 6 = 433.5 in²
Answer:
(1.5,-2.6)
Step-by-step explanation:
Given the polar coordinates (-3,60°).
Let our Cartesian coordinates be (x,y)
#We know that when converting the rectangular coordinates (x,y) to polar (r,θ), then:

#Using the illustration above, we can express our polar coordinates as:

#Solve simultaneously to solve for x and y:

Hence, the Cartesian coordinates are (1.5,-2.6)
Answer:19+3x
Step-by-step explanation:
4+3(5+x)
Open bracket
4+15+3x
19+3x
V ,= 4/3 πr³
solve for r
3V/4=r³
so r is the cubed root of 3V/4
