A paint can is a cylinder
surface area of a cylinder = <span>2(3.14) *</span><span> r^</span>2<span> + 2(3.14)</span><span> * r * h
SA = 2(3.14) * 8.5^2 + 2(3.14) * 8.5 * 24
SA = 6.28 + 72.25 + 6.28 * 8.5 * 24
SA = 1735.73 centimeters</span>
Answer:
Step-by-step explanation:
Given
Required
The sample mean
This is calculated using:
So, we have:
Simple interest formula:
Total = principal x (1 + rate x years)
10 years:
Total = 15,000(1+0.04x10)
Total = $21,000
8 years:
Total = 15000(1+0.04x8)
Total = $19,800
Savings = 21,000 - 19,800 = $1,200
Answer:
Explanation:
Identity: sec2θ=1+tan2θ
sec2(π2−x)−1=1+tan2(π2−x)−1
=tan2(π2−x)
Identity: tan(π2−θ)=cotθ
=cot2x
