Question

The diameter of a round dinner plate is 10 in. What is the area of the plate? can someone help with this prob?

Answer 1

Area = PI x R x R

Where PI is 3.14159 and R=radius (or half diameter).

Answer 2

Must be a pi plate! A= pi(r squared).  Nudge it up a little for the concavity, or get a calculus guy to help!

Answer 3

78,53981634 sq.in

Answer 4

the formula for area of a circle is pi(r^2)

so the r here is half of the ten

thus area is 25pi

Answer 5

the area of a circle is computed by multiplying PI(equivalent to 3.1416) to the square of its radius. The radius is half of its diameter so,

Area=PI (x) Radius (x) Radius

or

Area = PI (x) Diameter (x) Diameter (/) 4

Area = 3.1416 (x) 10 (/) 4

Area = 78.54 square inches

Answer 6

The area of a circle = pi times r squared.  The radius = 1/2 of the diameter.  So r = 5.

5^2 * pi = 25 pi or approximately 78.5398163

Answer 7

Most plates are not flat so this also must be considered in the calculation.....james the HOLLOW EARTH MAN
