Answer:

Step-by-step explanation:

The formula for arc length in terms of degrees is

A.L.=\frac{\theta}{360}*2\pi r and we have everything we need to fill in to find the angle measure.

123.53=\frac{\theta}{360}*56\pi which is the same as

123.53=\frac{56\pi \theta}{360} and

360(123.53)=56\pi \theta and

\frac{360(123.53)}{56\pi}=\theta so

θ = 253°

A nursery sells plants in flats. There are 6 plants in each tray. Each flat has six trays. The nursery sold 18 flats on Saturday
marshall27 [118]

For this case we have to:

There are 6 plants per tray.

There are 6 trays for each flat, so for each flat there are 6 * 6 = 36 plants.

Saturday day:18 flat * 36 plants = 648

Thus, on Saturday they sold 648 plants.

Sunday: 21 flat * 36plants = 756

Thus, on Saturday they sold 756 plants.

Thus, in total 648 +756 = 1404plants were sold.

Answer:

648 +756 = 1404 plants were sold.
