Question

find the diameter of a circle whose area is 962 .5 CM square​

Answer 1

Answer:

hey mate here's ur answer

let the radius of circle be r cm

then diameter = 2r

given, area of circle = 962.5 cm²

but area of circle = πr²

=> πr² = 962.5

=> (22/7)*r² = 962.5 [π = 22/7]

=> r² = (962.5/22)*7

=> r² = 43.75*7

=> r² = 306.25

=> r = 17.5

so, diameter = 2*17.5 = 35 cm

Answer 2

Answer:

35cm

Step-by-step explanation:

area = πr^2

=πd^2/4

=962.5

therefore, d^2=1225

therefore d=35cm.
