Answer:

1 unit

Step-by-step explanation:

The circumference of a circle can be found by multiplying the diameter by pi (around 3.14)

$c = \pi \: d$

If you rearrange this equation to find the diameter, you get:

$d = \frac{c}{\pi}$

If you add your numbers into this, you get:

$d = \frac{3.14}{\pi}$

As pi is around 3.14, you essentially end up with d = 3.14/3.14, and because any number divided by itself is equal to 1, we end up with the diameter being 1.

Answer:

<h2>6.28 units</h2>

Step-by-step explanation:

The diameter is twice the circumference, so it is 6.28.

Diameter measures the full circle from one side to the other, circumference only measures half of that.

A person on tour has dollar 360 for his daily expenses. If he extends his tour for 4 days, he has to cut down his daily expenses

Greeley [361]

Answer:

The original duration of the tour is 18 days.

Step-by-step explanation:

Let

the number of days spent be T

Daily expenses be D

Initially ,

total tour expenses was 360

$D \times T=360$

$D = \frac{360}{T}$ -------------(1)

If he extends his tour for 4 days, he has to cut down his daily expenses by dollar 3

$(D + 4) \cdot(T -3) = 360$ ---------------(2)

Expanding the eqaution(2)

DT-3D + 4T -12 = 360

Substituting the value of D

$(\frac{360}{T})T -3( \frac{360}{T}) + 4T -12 = 360$

$(\frac{360}{T})T -3( \frac{360}{T}) + 4T= 360 + 12$

$(\frac{360}{T})T -3( \frac{360}{T}) + 4T= 372$

$360 - ( \frac{1080}{T}) + 4T= 372$

$( \frac{1080}{T}) + 4T= 372 - 360$

$( \frac{1080}{T}) + 4T= 12$

$1080 + 4T^2= 12T$

Solving the quadratic equation we get

T = 18 and T = -15

T is the number of gays and it cannot be negative , hence T is 18

Substituting in equation (1) we get

$D = \frac{360}{18}$

D = 20

Solve for m m m Please help!!!

jarptica [38.1K]

Answer:

m∠ TRS = 60° , m∠ SRW = 120°

Step-by-step explanation:

First, find x

∠TRS = ∠VRW (vertically opposite angles are equal)

x + 40° = 3x

x - 3x = -40

-2x = -40

x = -40/-2

x = 20

m∠ TRS = 60° [x + 40 = 20+40 = 60]

m∠ SRW + m∠ TRS = 180° (linear pair)

m∠ SRW + 60° = 180°

m∠ SRW = 180° - 60°

m∠ SRW = 120°

hope this helps you

Gannon has deposited $742 in a savings account that earns interest at a rate of 3.4% compounded monthly. What will the account b

marta [7]

Firstly, solve the effective annual interest (ieff) with the equation,

ieff = (1 + i/m)^m -1

where i is the interest rate and m is the number of times the interest is compounded in a year. In this problem, m is 12

Substituting the values,
ieff = (1 + 0.034/12)^12 - 1 =0.03453

To solve for the future (F) amount of the present investment (P),

F = P x (1 + ieff)^n

where n is number of years.

F = ($742) x (1 + 0.03453)^15

Thus, the answer is $1234.76.
