Answer:
90π units²
Step-by-step explanation:

Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,
= 2πrh
= 2π(3)(12)
= 72π units²
Hence,
Surface area = 18π + 72π = 90π units²

You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)
Step-by-step explanation:
Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120
, ,=42candles
How much farther than Shamir will Juliet travel in one hour is : b. 3 miles.
<h3>Distance</h3>
1 hour= 60 minutes
Given:
Difference in 10 minutes=1/2 mile
Hence:
Difference in one hour=1/2×(60/10)
Difference in one hour=1/2× 6 mile
Difference in one hour=3 miles
Therefore how much farther than Shamir will Juliet travel in one hour is : b. 3 miles.
