Answer:
To find the radius, divide the diameter by 2;
V={π(r^2)h}/3
={3.14(4^2)*9 cm^3}/3
=3.14*16*3 cm^3
=150.72 cm^3
We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.
This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.
To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:
A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)
Answer:
-3
Three feet below the initial elevation
Step-by-step explanation:
The initial elevation is 224 feet.
We take descent to be negative and ascent to be positive.
The numerical addition expression is

We simplify this to obtain:

The negative sign means Sally is 3 feet below his initial elevation
The quotient of the provided division in which binomial is divided by a quadratic equation is x+2.
<h3>What is the quotient?</h3>
Quotient is the resultant number which is obtained by dividing a number with another. Let a number <em>a</em> is divided by number b. Then the quotient of these two number will be,

Here, (a, b) are the real numbers.
The given division expression is,

Let the quotient of this division problem is f(x). Thus,

Factor the numerator expression as,

Thus, the quotient of the provided division in which binomial is divided by a quadratic equation is x+2.
