Find the area of the semicircle.

the area of the semicircle is 4.5π

Step-by-step explanation:

Step 1: Find the radius

Radius = Diameter divided by 2 =6/2=3

Step 2: Find the area of the full circle

                             =π3 to the power 2

                             =9π

Step 3: Find the area of 1/2 of the circle.

9/2π = 4.5π

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
