Answer:
Area of the garden:
Explanation:
Given the below parameters;
Length of the rectangle(l) = 23 ft
Width of the rectangle(w) = 14 ft
Value of pi = 3.14
Since the width of the rectangle is 14 ft, so the diameter(d) of the semicircle is also 14 ft.
The radius(r) of the semicircle will now be;
Let's now go ahead and determine the area of the semicircle using the below formula;
Let's also determine the area of the rectangle;
We can now determine the area of the garden by adding the area of the semicircle and that of the rectangle together;
Therefore, the area of the garden is 398.93 ft^2
Answer:
5.3
Step-by-step explanation:
-2r+3s
Let r=-8.2 s=-3.7
-2(-8.2) +3(-3.7)
16.4-11.1
5.3
Answer:
18.84 units
Step-by-step explanation:
the formula for the circumference is 2× pi × radius.
the radius is half the diameter, so the formula would be 2×pi×6/2
the answer to 2 decimal places is therefore 18.84 units
Answer:
<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>
Step-by-step explanation:
Here,
x = the temperature of water in °C
y = the number of insect larvae in the water
The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.
At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.
As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.
Therefore, at y intercept or at 0°C there were 400 larvae.
