Answer:

96 in²

Step-by-step explanation:

Lateral surface area

= 3 rectangles

(4×8) + (3×8) + (5×8)

32 + 24 + 40

96 in²

Answer:

96 inches squared

Step-by-step explanation:

The lateral area of the prism is the part that is not the bases. The bases here are the triangles, which means the lateral area will be the rectangles.

There are 3 rectangles with dimensions:

- 5 in by 8 in

- 4 in by 8 in

- 3 in by 8 in

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. Calculate the areas:

- 5 * 8 = 40

- 4 * 8 = 32

- 3 * 8 = 24

Add these up:

40 + 32 + 24 = 96

The answer is 96 inches squared.

The formula for the area of a circle is A equals xr2 this formula allows you to find the area of a circle if you know the radius

iVinArrow [24]

Answer:

The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$

Step-by-step explanation:

Given as :

The formula for the area of circle = $\pi$ × radius²

I.e A = $\pi$ × radius²

Now If we know radius then

Area calculated as A= $\pi$ × radius²

If we know Diameter then

Area calculated as $\pi$ × ( $\dfrac{\textrm Diameter}{2}$ )²

Or, A = $\pi$ × ( $\dfrac{\textrm D}{2}$ )²

I,e A = $\frac{\pi D^{2} }{4}$

If we know the circumference then

∵ circumference = c = 2 × $\pi$ × radius

or, c = 2 × $\pi$ × r

from here we calculate radius

I.e r = $\frac{c}{2\pi }$

And So , Area ( A ) = $\pi$ × radius²

I.e A = $\pi$ × ( $\frac{c}{2\pi }$ )²

Or, A = $\frac{c^{2} }{4\pi }$

Hence The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$ Answer

The area of the square represented in item 1 is revised to be 90.0 in.2. note that the original grid spacing no longer applies.

ahrayia [7]

By definition, the area of a square is given by:
A = L ^ 2
Where,
L: side of the square.
Substituting
90 = L ^ 2
Clearing L we have:
L = root (90)
L = 9.486832981 in
Answer:
The side length of the square is:
L = 9.486832981 in
