what is the approximate volume of a tree trunk if the trunk is 13 feet tall with a circumference of 4.5 feet

Answers

Answer 1
Answer:

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
Answer 2
Answer: Volume of a cylinder is \pi r^(2) h
C = \pi 2r
4.5/2\pi = r
0.7162 = r
\pi r^(2) 13 = 20.91

1a) Which equation demonstrates the commutative property of addition for complex numbers? A: (5 - 10i)[(0 - 10i) +(5 +0i)] = [(5 - 10i)(0 - 10i)]+[(5 - 10i)(5 +0i)]


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)

Answers

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.

Select the correct solution set.-7x ≥ 56

{x | x ≤ -8}
{x | x ≥ -8}
{x | x ≥ 8}

Answers

-7x ≥ 56.

Divide both sides by -7, and the inequality sign reverses, because we are dividing by a negative number.

The sign also reverses when you multiply both sides of inequality by a negative number.

-7x/-7   ≤   56/-7

x  ≤ -8

The answer is the first option.

{x | x ≤ -8}

This simply means x, such that x is less than or equal to -8.

I hope this helped.
