The diameter of a circle is 2.8 yards. What is the circle's area?

Use 3.14 for π and round your answer to the nearest hundredth. Please explain.

Answer 1

3.14*1.8*1.8= answer
cause formula is pie *r*r

Answer 2

diameter = 2.8
radius = 1.4
area of circle = pi*r^2
3.14*1.4*1.4

Answer 3

yehh sorry 1.4

Answer 4

your units should be "square yards"

Answer 5

(if they give you diameter, just remember to divide in half to get the radius, so you can plug it into the equation...)

Answer 6

you should have 2 numbers after the decimal point to round to the nearest hundredth.

Answer 7

thanks
