Question

A circle has a radius of 12 centimeters. If 6/7 of the circle is cut away, what is the area of the remaining portion?

Answer 1

It is obvious that 1/7 of the area is remaining.
First calculate the area then multiply that by 1/7.

Answer 2

51.43 am i going right?

Answer 3

A = pi*r^2
= 452.4 (1dp )

1/7 of the area remaining so (1/7) * 452.4 = 64.6 (1dp) cm^2

Answer 4

oh

Answer 5

\( \color{Black}{\Rightarrow\Large {3.14 \times 144 \over 7} }\)
