Answer:
V=21.17³
Step-by-step explanation:
c=2πr
4.5=2(3.14)r
4.5/6.28=6.28r
6.28s cancel each other out
7.16=r
round
V=πr²h
V=21.17³
four to the power of the fraction sixteen over eighty one square inches
two to the power of eight ninths square inches

Step-by-step explanation:
The answer to ur question is b
B a + 2b + 3c + 2d + e
C b + d + e
D a - c - e
Answer:
Step-by-step explanation:
B: (10 - 5i) + (5 - 10i) = (5 - 10i) +(10 – 5i)
C: (5+ 10i)+(- 5 - 10i) = 0+ Oi
D: [(0 - 5i)+(5-i)] +(5 +i) = (0 - 5i)+[(5 - i) +(5+i)]
1b) Which of the following demonstrates the commutative property of multiplication?
A: (8+6i)(4+2i)=(4+2i)(8+6i)
B: (7-6i)(0+2i)=(7+2i)(0-6i)
C: (2+8i)(2-8i)=20
D: (-5+3i)(-1+i)=(5-3i)(1+i)
Answer:
The answer to 1a is B and the answer to 1b) is A.
Step-by-step explanation:
I got my answer right on the quiz. So, it's actually a lot easier than it seems. Imagine 4+2=2+4 or (8)(4)=(4)(8). That is commutative property of addition and multiplication just simper. In this case B and A are the same thing just with complex numbers.
