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
The ratio of the surface areas are 361/81.
surface area is a 2D measurement.
similarity is a 1D ratio.
square root of 361/81 is 19/9.
Answer:
D
Step-by-step explanation:
The answer is graph D because in the word problem it says, "more than three copies". We can also see that we need to find how many copies are made in 4 hours. Since it says more than and we do not have another number, we will multiply 3 and 4.
3 x 4 = 12
This is a line graph. An enclosed circle on a number would mean that this line includes the number. This circle is open, not enclosed so 12 is not a part of the line for graph D.
Since it says more than, this open circle makes sense, because it was more than 3 books, but not 4 books. This means it can range anywhere after 3. (examples: 3.1 books, 3.5 books, 3.8 books) this means it can also range anywhere after twelve.
This combined shows us that graph D is the answer.
Answer:
I don't understand this question...
Step-by-step explanation:
But If you want a fraction greater than 100% than you have to find a percentage that is greater than 100% and convert it into a fraction
Answer:
π(12.1)²
Step-by-step explanation:
12.1 is the radius
Formula for base = πr²
= π(12.1)²
