Standard plywood is 4x8. Meaning it will cover 32 square feet. So you will need four full sheets.
Each sheet = 4' x 8' = 32 square feet20 square meters = 215.278 square meters (rounded)20 sq mtr/32 sq ft = 6.727 sheets (rounded)

A 30 foot circle covers about 707 square feet. 23 pieces would technically cover that. I'd get 30 of them so I wouldn't have to cut any of them.
The answer depends on the units used for 4x8 which are unspecified. The answer will vary according to whether those units are inches, metres, parsecs, etc.
Assuming the circle has a diameter of 12', its area is pi*62 = 113.1 sq ft (approx). Four pavers of 4ft x 8 ft, each with an area of 32 sq ft will cover 128 sq ft in all. However, it will be necessary to use the offcuts.
104 sq feet = 104*12*12 square inches which will require 104*12*12/(4*8) = 468 bricks.
