Help me for brainlist please

a. 312cm^2

Step-by-step explanation:

You find the area of the rectangle

4 * 6 = 24

Then you find the area of the trapezoid

(10 + 6) * 5 / 2 = 40

Multiply 40 * 2 since there are two trapezoids

40 * 2 = 80

Add the of one bow

80 + 24 = 104

multiply it by 3 since you need 3 bows

104 * 3 = 312

Your answer is 312

A = 0.785m²

B = 31400cm²

C = 7850cm²

D = 785,000mm²

Use the fomula to find the area.

If you are having trouble finding the radius divide the diamater by two.

For refrence use 3.14 as pi when multiplying:)
