I'm sure the measurement was made in grams because:
1. most cell phones weigh between about 100 and 150 grams
2. there's no cell phone that weighs 113 kg, 113 pounds, 113 ounces etc.
C= 2πr, and 2r = D (diameter). So, you can also use this equation: C =D<span>π
Since we know the diameter, and we know the value of </span><span>π, we can easily calculate the value of circumference.
C = D</span><span>π
C = 3.21</span><span>π
</span><span>This means that the correct answer is B. 3.21 pi</span>
Question 1: The correct answer is Option 3: 20
Question 2: The correct answer is Option 3: 27
Step-by-step explanation:
We put the term number as value of n in explicit formula to find the term.
<u>Question 1:</u>
Given

To find t4, we will put t=4 in explicit formula

The correct answer is Option 3: 20
<u>Question 2:</u>
Given, the explicit formula

We have to find the 5th term, putting n=5 in the explicit formula

The correct answer is Option 3: 27
