X = -3
y = 3*sqrt(3)
r = sqrt(x^2 + y^2)
r = sqrt((-3)^2 + (3*sqrt(3))^2)
<span>r = sqrt(9+27)
</span><span>r = sqrt(36)
</span>r = 6
theta = arctan(y/x)
<span>theta = arctan(3sqrt(3)/(-3))
</span>theta = arctan(-sqrt(3))
theta = -60 degrees which is coterminal to 300 degrees
So the polar form is (r,theta) = (6, 300)
Something like 36÷3 = (3)÷3=1 and (6)÷3=3 you put 1 and 3 together to make 13
What expression ? There isn’t one
Answer:1072.3
Step by step:
use the hemisphere formula which is 2/3*pie*r^3
substitute 8 centimeters into the equation.
