Question

A small metallic plate is of 7 m radius with a hole of 1.5m radius . what is the area of the plate?​

Answer 1

44

Step-by-step explanation:

pi x (radius sq.) , where pi is 22/7

Answer 2

Answer:

= 146.87 m^2

Step-by-step explanation:

the formula for the area of a circle is Pi x radius^2

so, using the formula,

pi x 7^2 = 49 pi

BUT you have to take away the area of the hole!!!

so, pi x 1.5^2 = 9/4 pi (to get the area of the hole)

then, do 49 pi - 9/4 pi = 146.869..

round to a 2 decimal places.

= 146.87 m^2 --> dont forget to give units :)

Hope this assists you! <3
