The area of a 2D form is the amount of space within its perimeter. The lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m². The surface area of the cylinder will be 414 in².
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
A.) The area of the lateral faces are:
Latera area of the triangular prism = (38×7)+(38×8.06)+(38×4) = 724.28m²
The total area of the prism is:
The total area of the prism = Lateral Area + Area of the base face
= 724.28m² + 2(0.5×7×4)
= 724.28m² + 28m²
= 752.28m²
Hence, the lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m².
B.) The surface area of the cylinder can be written as,
Surface Area = 2πrl + 2πr²
= (2×π×9×14) + (2×π×9×9)
= 252in² + 162in² = 414in²
Hence, the surface area of the cylinder will be 414 in².

Step-by-step explanation:
Hey there!
From the given figure;
An exterior angle is 127°.
To find: value of"X"
Now;
x+127° = 180°. [Being linear pair]
or, X = 180° - 127°
or, X = 53°
Therefore, the value of "X" is 53°.

First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
