The radius of a circle measures 15 ft. What is the circumference of the circle?
Pie

Answer:

\boxed {\tt 94.2 \ feet}

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

c= \pi d

where d is the diameter. We are given the radius, so let's find the diameter.

The diameter is twice the radius.

d=2r

The radius is 15 feet.

d= 2 * 15 \ ft

Multiply.

d= 30 \ ft

Now we know the diameter. Substitute 30 feet in for d.

c= \pi d

c=\pi * 30 \ ft

We are using 3.14 for pi, so substitute it in.

c=3.14 * 30 \ ft

Multiply.

c= 94.2 \ ft

The circumference of the circle is 94.2 feet.

How would I find x, I know it's an isosceles triangle but I so not know how to solve for it?????​
Wittaler [7]

Answer:

x=7 (if your teacher cares it could + or - 7)

Step-by-step explanation:

Okay, since it's a 90 degree triangle you can use the Pythagorean theorem

( a^2 + b^2 = c^2)

Since it's an isosceles triangle the other side is x because it's the same value.

x^2 + x^2= (7\sqrt{2} )^2

Add the left side

2x^2= 7^2 + \sqrt{2}^2 roots and square roots cancel each other out

So -> 2x^2= 49 x 2 =98

just solve for x.

x^2 = 98/2

x^2= 49

Square root both sides

x= 7
