Question

The radius of the circular space is 4.5. Joanna will plant 40 flowers per square meter of space . She will plant 4 times as many red flowers as the white flowers. How many red flowers will she plant?

Answer 1

A = π(4.5²) = 20.25π = about 63.62 m²

(40 flowers/m²)(63.62 m²) = 2,545 flowers

Let w be the number of white flowers.

4w + w = 2,545

5w = 2,545

w = 509 white flowers

4w = 2,036 red flowers
