Question

the radius of a circle is 7cm find its area​

Answer 1

Answer:

154cm²

Step-by-step explanation:

1) Given

radius = 7cm

Area of a circle = πr²

(apply the formula) (π=22/7 or 3.14 (when you divide 7 by 22 you get 3.14) (you can use both if the given questions doesn't say you to use a particular one :))

so,

= 22/7 x 7cmx7cm

cut it out

= 154cm²

therefore area of the Circle is 154cm²
