Assuming you would like to find the volume . . . . .

Answer:

113.04

Step-by-step explanation:

To find volume, the formula is pi x r^2.

Let's replace the values.

3.14 * 6^2

Note that the radius is 6 since r = 1/2 d.

Now we just need to solve.

= 3.14 * 36

= 113.04

Assuming you want to solve for surface area . . . . .

The formula is long but it is:

SA =2πrh+2πr^2

Replace the values.

SA = 2 (3.14)(6)(11.5) + 2 (3.14)(6) ^2

Simplify.

6.28 (69) + 6.28 (36)

= 433.32 + 226.08

= 659.4

A Mexican restaurant sells quesadillas in two sizes: a "large" 10 inch-round quesadilla and a "small" 5 inch-

elena-14-01-66 [18.8K]

Answer:

Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^2$

where

r is the radius

step 1

Find the area of the 10 inch-round quesadilla

we have

$D=10\ in$

$r=10/2=5\ in$

substitute

$A=\pi (5)^2$

$A=25\pi\ in^2$

step 2

Find the area of the 5 inch-round quesadilla

we have

$D=5\ in$

$r=5/2=2.5\ in$

substitute

$A=\pi (2.5)^2$

$A=6.25\pi\ in^2$

step 3

Which is larger, half of the 10-inch quesadilla or the entire 5-inch quesadilla?

Compare

half of the 10-inch quesadilla is equal to ----> $\frac{1}{2}(25\pi)=12.5\pi\ in^2$

the entire 5-inch quesadilla ----> $6.25\pi\ in^2$

therefore

Half of the 10-inch quesadilla is greater than the entire 5-inch quesadilla
