Part A:
The circumference of the circle is 197.92.
Explanation:
The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.
Part B:
The area is 3117.25 square cm.
Explanation:
The formula for area of a circle is A= πr ². Inserting the numbers, it is A=3.14 x 31.5 ². Therefore the answer is 3117.25 cm ².
Answer:
Find the area of the trapezoid below.
Step-by-step explanation:
This is a common multiplication problem. Imagine P(4) as x, and Q(4) as y. You are plugging them into the equation x*y. Since x is equal to 13, and y is equal to 8, you are going to plug them into their corresponding variables and multiply. 13 * 8 = 104. The answer is 104.
