The face of a penny has a diameter of 4.2. What is the measurement closest to the circumference of the penny? *
10 points
O 13.2
6.6
13.8
O 5

Work Shown:

pi = 3.14 approximately

d = diameter = 4.2

C = circumference of circle

C = pi*d

C = 3.14*4.2

C = 13.188

C = 13.2

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,

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
