Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
Answer:
A is 10 and B is 35
Step-by-step explanation:
multiply the width or length by 1.25
Square Perimetre = Side x 4
So a length of a square ground is 160/4 = 40 (m)
Answer:
