Answer:

<h2>Yes the circumference is about times greater than their diameters</h2>

Step-by-step explanation:

We will approach this problem by doing a check

Say the diameter of a circle is 4 cm

Hence the radius is 3 cm

We know that the circumference is $C=2\pi r$

$C=2*3.142*2= 12.57cm$

The circumference is about 3 time bigger than the diameter

Let us try another case say the diameter is 6 cm

The radius is 3 cm

$C=2*3.142*3= 18.85cm$

SEE IMAGE! Two lines below intersect to form four angles, as shown. The measure of angle 2 is 114°. What is the sum of the measu

o-na [289]

ANSWER:

Angles 2 and 4 are vertical angles, which means they have the same angle measure because they are opposite of each other. So angles 2 and 4 are both 114 so that makes 228. All of the angles have to make 360, so 360 - 228 = 132. Then, 132/2 because there are two angles. That makes 66. And angles 1 and 3 are also vertical angles so they are also the same

The answer is 132

$300 invested at 12% compounded monthly after a period of 1.5 years

GalinKa [24]

Answer: $358.8 to the nearest tenth

Step-by-step explanation:

Compound interest is calculated by Where: A = P(1 + r)t

Where P= 300, r= 12% = 0.12, t= 1.5 years

Slot in the figures

300 (1 + 0.12) 1.5

300 (1.12) 1.5

300x 1.12

336e1.12

A = $ 358.84

Montano1993 [528]

Answer:

x=45

Step-by-step explanation:

Each triangle had 180 degrees in all and the picture shows it has a right angle. 180-90=90

90/2=45

Because there are two angles left without measurement.

The question, Find the image vertices for a dilation with center (0, 0) and a scale factor of 4.

Alexeev081 [22]

Answer:

Answer is A(-3/4, 1/4), B(1,3/4), C(1/2,3/4) D(1/4,1)

Step-by-step explanation:

From the attached diagram, the coordinates are:

A(-3,1), B(4,-3), C(2,3), D(1,4)

The image is gotten by dividing the coordinates by the scale factor 4 to get the above answer
