Answer:
To find the circumference of a circle, your equation is 2*pi*radius
C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)
C=12.56 ft
To find the area of a circle, your equation would be pie*r^2
A=3.14*2^2
A=3.14*4
A=12.56 sq. ft

Answer:
19.25ft
Step-by-step explanation:
area = length x width so 3.5 x 5.5 = 19.25
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.
The first one ,to substitute 3xy from -16 ...so divided both side by 3 .so, (xy =-5.33). the second one,5xy =-20. so,divided both sides by 5 so xy = -4....
