Answer:
The surface area of the prism is <u>480 in²</u>.
Step-by-step explanation:
Given:
The prism dimensions are 8in 15in 17in and 9in.
Now, to find the surface area:
So, to get the surface area we put formula:
a=8in, b=15in, c=17in and h=9in.
Surface area = 2A+(a+b+c)h.
Whereas,
And,
<em>Now, we find </em><u><em>s</em></u><em> first:</em>
<em>Then, we get</em><u><em> A </em></u><em>:</em>
<em>On solving we get:</em>
Now, putting the value of A in the formula to get the surface area:
Therefore, the surface area of the prism is 480 in².
Things we need to keep in mind in order to plot a point :
- x - coordinate of the point shows its distance from origin in horizontal direction.
- y - coordinate of the point shows its distance from origin in vertical direction.
Signs of the coordinates shows which side it lies on.
- if x coordinate is positive then the point lies on right side of y - axis and if it is negative then it lies on left side of y - axis.
similarly,
- if y coordinate is positive then the point lies above the x - axis , and if it's negative then it lies on down the x - axis.
Now, let's proceed ~
First check out its x - coordinate on origin and move up or down according to its y - coordinate and you will get your required point.
So, for point (1 , 0) it has y - coordinate = 0, so it lies on x - axis at the x - coordinate of 1.
Answer:
66 cm
Step-by-step explanation:
Let's define the circumference first.
It is the boundary of any curved geometric figure specially circle.
We are given the diameter of the circle in the diagram
The diameter is:
d = 21 cm
to find the circumference, we have to find the radius of the circle first.
As radius is half of diameter
d = r/2
= 21/2
= 10.5 cm
The formula for circumference is:
The circumference is 66 cm ..
