Answer:
Area = 254.469
Step-by-step explanation:
9 squared equals 81
81 x 3.14 = 254.469
I use the formula A= 3.14xr2
Step-by-step explanation:
A. 18√2
= 25.4558441227
B. 18/√3
= 6√3
= 10.39230485
C. 18√2 /√3
= 6√6
= 14.69693846
D. 18 · √3 / √2
= 9√6
= 22.04540769
Answer:
32 squared units
Step-by-step explanation:
The composite given in the figure consist of 3 triangles and 1 square shape.
To calculate the area of the composite shape, let's calculate area of each shape and then add all together.
==>Area of the square (Q): s²
s = 2
Area = 2² = 4 squared units
==>Area of biggest triangle (B): ½*b*h
b = 2+2+6 = 10
h = 4
Area = ½*10*4 = 5*4 = 20 squared units
==>Area of medium triangle (M): ½*b*h
b = 2
h = 6
Area = ½*2*6 = 6 squared units
==>Area of smallest triangle (S): ½*b*h
b = 2
h = 2
Area = ½*2*2 = 4/2 = 2 squared units
==>Area of composite shape = Q+B+M+S = 4+20+6+2 = 32 squared units
