Answer:
20 square meters
Step-by-step explanation:
area = length x width
area of grass = 4 x 4 = 16
area of grass and cement = 6 x 6 = 36
<em>Now you subtract to find the area of the cement.</em>
36 - 16 = 20

Answer:
Parallel sides
Step-by-step explanation:
A rectangle has all of its interior angles equal to each other and inclined at a degree of 90.
The two opposite sides of a rectangle are parallel to each other.
Parallel lines are lines that will never meet, no matter how long that they are extended.
If we can extend the two sides of the rectangle facing each other, we will be able to see that they will never meet no matter how far they are extended.
Thus, the rectangle has 2 pairs of parallel lines
Answer:
∫₋₃¹ π y⁴ dy
Step-by-step explanation:
If we slice the solid shape, we get circular cross sections or disks. The thickness of each disk is dy. The radius of each disk is x. So the volume of each disk is:
dV = π r² h
dV = π x² dy
Since x = y²:
dV = π y⁴ dy
The total volume is the sum of all the disks from y=-3 to y=1.
V = ∫ dV
V = ∫₋₃¹ π y⁴ dy
Answer:
A) A[p(t)] = 36πt²
B) 7234.56 square units
Step-by-step explanation:
<u>Given functions</u>:
<u>Part A</u>
To find the area of the circle of spilled paint as a function of time, substitute the function p(t) into the given function A(p):
<u>Part B</u>
Given
Substitute the given values into the equation for A[p(t)} found in part A:
Therefore, the area of spilled paint after 8 minutes if 7234.56 square units.
