A landscaper is building a circular flower bed. The flower bed has a diameter of 8 feet.
Which of the following models best represents the amount of border needed to go around the edge of the flower bed?
A company’s logo was designed using circles of 3 different sizes. The diameters of two of the circles are shown.
Which measurement is closest to the area of the largest circle in square centimeters?
56.52 cm2
141.30 cm2
1,017.36 cm2
254.34 cm2
in all cases,
C = πd
I can't see the circles, but use the above formula to find the circumference. For the area,
A = πr^2 = 1/4 πd^2
