Answer:
3) 16π cm²
4) 240.625 cm²
Step-by-step explanation:
<em>3. For this problem I'm going to use the formula Area = π × r²</em>
<em>To start off, I'm going to input our value of radius which is 4cm.</em>
π × 4²
<em>Finally, I'm going to square our value "4"</em>
16π cm²
<em>(I'm going to "leave my answer in terms of π" as the problem states but if you need the complete answer it would be </em>about 50.24 cm²
<em>4. For this problem I'm going to use the formula Area = π × (d/2)²</em>
<em>To begin, I will divide our diameter by 2 to find the radius.</em>
17.5/2 = 8.75
<em>Next, we are going to square our now, radius.</em>
8.75² = 76.5625
<em>Now, we have to multiply our squared radius by π (in this problem it states to use 22/7, so that's what we'll do :)</em>
76.5625 × 22/7 = 240.625 cm²
<em>So! This is our final answer!</em>

Step-by-step explanation:
Assume length of side 2 = L
Area of parallelogram is Height x L
So, 72 = 8 x L
L = 9

Step-by-step explanation:
The roller coaster can accommodate 9 riders every 4 minutes. 36 riders in 16 minutes, 54 riders in 24 minutes, and 72 riders in 32 minutes all follow the common ratio.
Answer:
Step-by-step explanation:
Let C be the number of correct answers
Let B be the number of questions not answered
Let W be the wrong answers
Total = 2*C + B - W
It's a trinomial. There are three unrelated terms.
