Well, to find the circumference of a circle, we can use the formula
C=2 $\pi$ r.
So just plug in 3.5 into the formula.
C=2 $\pi$ 3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.
Hope I helped!

Why is the value of q?

Rudiy27

Given:

QSR is a right triangle.

QT = 10

TR = 4

To find:

The value of q.

Solution:

Hypotenuse of QSR = QT + TR

= 10 + 4

= 14

Geometric mean of similar right triangle formula:

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$$\Rightarrow \frac{14}{q} =\frac{q}{4}$

Do cross multiplication.

$$\Rightarrow14\times 4 =q\times q$

$$\Rightarrow 56 =q^2$

Switch the sides.

$$\Rightarrow q^2 =56$

Taking square root on both sides.

$\Rightarrow q =2 \sqrt{14}$

The value of q is $2 \sqrt{14}$ .

Convert y - 3 = 1/3 (x - 6) to standard form.

MAXImum [283]

Y - 3 = 1/3(x - 6)
y - 3 = 1/3 x -2
y = 1/3 x - 2 + 3
y = 1/3 x - 1

Answer ⇒ y = 1/3 x - 1

3(2^x) = 6^2x <br>How do you solve this?

iragen [17]

$3(2^x)=6^{2x}$
$3(2^x)=(3\times2)^{2x}$
$3(2^x)=3^{2x}2^{2x}$
$\ln(3(2^x))=\ln(3^{2x}2^{2x})$
$\ln3+\ln2^x=\ln3^{2x}+\ln2^{2x}$
$\ln3+x\ln2=2x\ln3+2x\ln2$
$\ln3=2x\ln3+2x\ln2-x\ln2$
$\ln3=x(2\ln3+\ln2)$
$x=\dfrac{\ln3}{2\ln3+\ln2}$
