Answer:
160π/3 units² ≈ 167.55 units²
Step-by-step explanation:
The appropriate area formula is ...
A = (1/2)r²θ
Filling in the numbers, you have ...
A = (1/2)(8²)(5π/3) = 160π/3 ≈ 167.55 . . . . square units
Answer:
Step-by-step explanation:
We know 
is a complex number and is defined by 
∴
Answer:
A rational number is said to be closed if the subtracted values and the result obtained are rational. Hence, the equations which supports the condition are :
5.5 - 0.5 = 4
5√4 - √4 = 4√4
Step-by-step explanation:
A.)
√8 - √8 = 0 ; the added values aren't rational and the result, Zero is not rational either.
B.)
5√4 - √4 = 4√4
5(2) - 2 = 2(2)
10 - 2 = 4
All the values in the expression are rational ; hence, it supports the assertion.
C)
5.5 - 0.5 = 4 ; all the values in the expression are rational, hence, it supports the fact.
2√3 - √3 = √3 ; the values in the expression are not rational, hence, it does not meet the condition.
Therefore, only options B and C supports the assertion.
Let me add that I learned most of this from Brainly a user named fichoh :)
