How many grams of seeds will it take to sow flowers in a round bed with a diameter of 3.4 if 12

How many grams of seeds will it take to sow flowers in a round bed with a diameter of 3.4 if 12 g of seeds are sown on 1m²?

1) First, we find the area of a round flower bed if its diameter = 3.4 m.

S = pi * r ^ 2 = pi * (d / 2) ^ 2 = 3.14 * (3.4 / 2) ^ 2 = 3.14 * (3/2 + 0.4 / 2) ^ 2 = 3.14 * (1.5 + 0.2) ^ 2 = 3.14 * 1.7 ^ 2 = 3.14 * 2.89 = 9.0746 m².

2) Determine how many grams of seeds will be required for sowing flowers in a round flower bed with an area of 9.0746 m², if 12 grams of seeds are sown per 1 m².

9.0746 * 12 g = 108.8952 g = 109 g.

This means that you need 109 grams of seeds for a round flower bed with a diameter of 3.4 m.
