Answer:
36 cm³
Step-by-step explanation:
V = lwh
you can separate the figure into a 2 ×2 × 3 rectangular prism on left which gives you a volume of 12
the remaining portion is 2 × 2 × 6 which gives a volume of 24
12 + 24 = 36 cm³
Answer:
126 cm^2
Step-by-step explanation:
Let's name the point where the two triangles meet on the horizontal line point Z. Then the area of the left triangle is ...
A(left) = (1/2)(XZ)(AX)
and the are of the right triangle is ...
A(right) = (1/2)(ZY)(YC)
Now, we know that AX = YC = (1/2)AD, so the sum of the two triangle areas is ...
A(triangle total) = A(left) +A(right)
= (1/2)(AX)(XZ +ZY)
Since XZ +ZY = AB, we have the total triangle area equal to ...
A(triangle total) = (1/2)((1/2)AD)(AB) = (1/4)(AD)(AB)
Now (AD)(AB) = 168 cm^2, so the <em>unshaded</em> area is ...
A(unshaded) = A(rectangle) -A(triangle total)
= 168 cm^2 -(1/4)(168 cm^2)
= 126 cm^2
The unshaded area in the figure is 126 cm^2.
Answer:
21
Step-by-step explanation:
9+[10+(5-4)x2]
= 9+(10+1x2)
= 9+(10+2)
= 21
The question is related to application of derivatives .
Let A represents the area and s represent the side length .
Differentiating both sides with respect to t
It is given that ds/dt = 4cm/s
Substituting the values of s, ds/dt and on multiplying them, we will get
dA/dt = 2(5)(4) = 40 cm^2/s
Therefore rate of change of area when area= and rate of change of side is 4 cm/s is 40
