I need help

C = 2(3.14)r

C = (3.14)d

Step-by-step explanation:

Circumference in terms of radius:

So replacing pi with 3.14 you would get 2(3.14)r

Circumference in terms of diameter:

So replacing pi with 3.14 you would get d(3.14)

the answer is 28

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
