Please help me‼️‼️‼️‼️‼️‼️‼️‼️‼️
galina1969 [7]

Step-by-step explanation:

1 m = 3.280839895... ft

therefore,

1 m² = 10.76391042... ft²

35 m² = 35 × 10.76391042... ft² =

= 376.7368646... ft²

the area of the circle is

pi×r²

r = 50/2 = 25 ft

so, the area of the red circle is

pi×25² = pi×625 = 1,963.495408... ft²

we need to paint it twice, so the area to be painted is twice the area of the circle

2×pi×625 = 3,926.990817... ft²

we need a many cans as the cover area of a single can fits into the total area to be painted :

3,926.990817... / 376.7368646... = 10.42369671... cans

we need to round this up to full cans.

so, we need 11 cans of red paint to give that red pad 2 coats of paint.
