How do you find the exact area of a circle having the given circumference of 3 pi

Answers

3.14 times the square of ur radius is equal to area of a circle. So in this case , they having the given circumference of 3pi , then u divided by 2 is ur radius. Radius is 1.5. 3.14 times 1.5 square or 3.24 times 1.5 times 1.5 it will get ur final answer. ( I don't have my calculator with me so I gave u a direction only )

In ΔTUV, the measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet. Find the length of TU to the nearest tenth of a foot.

Answers

Given:

Given that ΔTUV is a right triangle. The measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet.

We need to determine the length of TU.

Length of TU:

The length of TU can be determined using the trigonometric ratio.

Thus, we have;

$sin \ \theta=(opp)/(hyp)$

where $\theta=55^(\circ)$ , $opp=82$ and $hyp =TU$

Substituting the values, we get;

$sin \ 55^(\circ)=(82)/(TU)$

Simplifying, we get;

$TU=(82)/(sin \ 55^(\circ))$

$TU=(82)/(0.819)$

$TU=100.12$

Rounding off to the nearest tenth, we get;

$TU=100.1$

Thus, the length of TU is 100.1 feet.

1. what is the GCF of the terms of 8c^3+12c^2+10c? A.2
B.4
C.2c
D.4c

2. How can the polynomial 6d^4+9d^3-12d^2 be factored l?

Answers

Answer:

1. C. 2c

2. $3d^2(2d^2+3d-4)$

Step-by-step explanation:

A. We have been given an expression and we are asked to find the GCF of our given expression.

$8c^3+12c^2+10c$

Let us find factors of each of our given terms.

Factors of $c^3$ are $c*c*c$ ,

Factors of $c^2$ are $c*c$ ,

We can see that c is the greatest common factor of $c^3$ , $c^2$ and $c$ .

Factors of 8 are: 1, 2, 4, 8.

Factors of 12 are: 1, 2, 3, 4, 6, 12.

Factors of 10 are: 1, 2, 5, 10.

The greatest common factor of 8,12 and 10 is 2.

So let us factor out 2c from our expression.

$2c(4c^2+6c+5)$

Therefore, the greatest common factor of our given expression is 2c and option C is the correct choice.

2. We have been given a polynomial and we are asked to factor our given polynomial.

$6d^4+9d^3-12d^2$

We will pull out the greatest common factor of the terms of our given polynomial.

We can see that GCF of $d^4$ , $d^3$ and $d^2$ is $d^2$ .

The GCF of 6, 9 and 12 is 3.

So let us factor out $3d^2$ from our polynomial.

$3d^2(2d^2+3d-4)$

Therefore, the factored form of our given polynomial is $3d^2(2d^2+3d-4)$ .

If you pay attention 2 goes into 8, 10, & 12 and it looks like they all have one C. So what do you think it is lol?(:

Which is the solution to the equation 3.5 (2 h + 4.5) = 57.75? Round to the nearest tenth if necessary.

Answers

Answer:

h = 6

Step-by-step explanation:

Step 1: Distribute

7h + 15.75 = 57.75

Step 2: Subtract 15.75 on both sides

7h = 42

Step 3: Divide both sides by 7

h = 6
