A circle has a circumference of 907.46907.46 units. What is the diameter of the circle?
MAVERICK [17]
<h2>Answer:</h2>

<u>The diameter of circle is  </u><u>288.84 units</u>

<h2>Step-by-step explanation:</h2>

As we know

Circumference of circle = 2*pi*r

where r is radius of the circle

Arranging the equation

C = 2 π r

r = C / 2 π

r = 907.46 / 2 π

r= 144.42

Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units

The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length
Mademuasel [1]

Answer:

10.2 inches

Step-by-step explanation:

we know that

In this problem we have two cases

First case

The given lengths are two legs of the right triangle

so

a=12\ in, b=15\ in

Applying the Pythagoras Theorem

Find the length of the hypotenuse

c^{2}=a^{2} +b^{2}

substitute

c^{2}=12^{2} +15^{2}

c^{2}=369

c=19.2\ in

Second case

The given lengths are one leg and the hypotenuse

so

a=12\ in, c=15\ in

Applying the Pythagoras Theorem

Find the length of the other leg

b^{2}=c^{2} - a^{2}

substitute

b^{2}=15^{2} - 12^{2}

b^{2}=81

b=9\ in

Find the difference between the two possible lengths of the third side of the triangle

so

19.2-9=10.2\ in
