Answer:
First know the formula for the area of a circle;
<h2>A = πWhere 'π' represents pi(3.14 or 22/7), and 'r' stands for the radius being squared.
For the first problem, we can see that 12 is our <u>diameter</u>.
And to find the radius, we need to find 1/2 of the diameter (half of the diameter), so;
D/2 = R
Replace with actual values;
12/2 = 6, <u>6</u> is our <u>radius</u>.
Now we plug this into our formula:
A = π
A = 3.14(6^2)
A = 3.14(36)
A = <u>113.04 centimetres</u> is the area of the circle.
For the second problem, we can see that 18 is our <u>diameter</u>.
And to convert the diameter into the radius, we do what we did to the past problem, find 1/2 of the diameter.
So;
D/2 = R
18/2 = 9, <u>9</u> is our <u>radius</u>.
Now we plug this into our formula:
A = π
A = 3.14(9^2)
A = 3.14(81)
A = <u>254.34 inches</u> is the area for this circle.
For the third problem, we can see that our radius is already given, 5.
So now we just simply and easily plug this into our formula;
A = π
A = 3.14(5^2)
A = 3.14(25)
A = <u>78.5 meters</u> is the area for this circle.
The question is incomplete. Below you will find the missing graph.
The lowest value of the range of the function shown on graph is (B) -2.
Graph is the pictorial representation of the function or mathematical relation.
The lowest value of the graph is the value of y when gives the least value.
From the given graph we can clearly see that at the graph of the given function approaches the least value which is -2.
So the lowest value of the range of the function shown on the graph is -2.
Hence the correct option is (B).
