The circumference of a circle is 15 ft. what is the length of the radius? use 3.14 for π. round your answer to the nearest tenth of a foot.

The radius of the circle is 2.4ft

Step-by-step explanation:

circumference of circle = 2πr

circumference = 15ft

2πr = 15

(2×3.14)r = 15

6.28r = 15

r = 2.4ft (near. tenth)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
