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???

22/7 * (28/2)^2 = 22 * 14 * 2 ... cm^2

Thqnks guys

Help me plsssss
