Answer:
The lateral area of a cone equals
PI * radius * slant height
=PI * 3 * 5
lateral area = 47.1238898038 square centimeters
Step-by-step explanation:
To find the surface are, we can add up the area of all of the sides.
Top:
4in x 9in = 36in^2
Bottom:
<span>4in x 9in = 36in^2
</span>
Front:
5in x 9 in = 45in^2
Back:
<span>5in x 9 in = 45in^2
</span>
Right:
4in x 5in = 20in^2
Left:
<span>4in x 5in = 20in^2
</span>
Adding them all together:
36+36+45+45+20+20 = 202in^2
The surface area of the prism is 1. 202 in^2
Denominators can be multiplied to make:
ax < cb
We divide both sides by a to cancel it out and:
The answer: x <
