Step-by-step explanation:
Assuming this pizza is a circle, we can use this formula for area:
1. Find Radius
We are given the diameter: 12 inches, but the formula uses radius.
The radius is half the diameter, or:
2. Calculate Area
Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.
Solve the exponent.
- (6 in)²= 6 in* 6 in= 36 in²
Multiply.
3. Round
The question asks us to round to the nearest tenth.
The 4 in the hundredth place tells us to leave the 0 in the tenth place.
The area of the pizza is about 113.0 square inches.
Answer:
<u>9 parts</u> of beans and <u>12 parts</u> of ground beef is in the chilli.
Step-by-step explanation:
Given:
In a pot of chilli, there are 3 parts of beans to every 4 parts of ground beef.
If a total of 21 combined parts we're used to make.
Now, to find each ingredients is in the chilli.
As, given there are 3 parts of beans to every 4 parts of ground beef.
Let the beans be
And the ground beef be
Total combined parts = 21.
Now, to get the each ingredients we solve an equation:
<em>Dividing both sides by 7 we get:</em>
<em>The beans = </em><em />
<em>The ground beef</em> = .
Therefore, 9 parts of beans and 12 parts of ground beef is in the chilli.
