Rectangular Prisms and Volume Quiz Part 2
A circle has a diameter of 28 centimeters.
Estimate the area of the circle. Use
22/7 for π
(π * d^2) / 4
pls pls pls pls
88 cm
plsssssssss help
explain pls
is that right?
radius =14
r^2 = 196
area = 196*22/7 = appr. 200 * appr 3 = about 600
actual answer = 14^2 * π = 615.752...
Strange question asking for estimate, then using 22/7.
You would probably use a calculator anyway which makes "estimating" not
necessary.
btw, who uses 22/7 for π in this day and age???
