Answer:
Solution given:
radius [r]=2cm
height [h]=8cm
total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
- 2πr(r+h)
- 2π*2(2+8)
- 40π or 125.66cm²
<u>total surface area of cylinder</u><u>40π or 125.66cm²</u><u>.</u>
Answer:
5/11
Step-by-step explanation:
Probability is the chance that something will happen. Basically, it answers the question of how many times an event will occur in a given number of opportunities.
In this example, the word "GEOMETRICAL" has 11 letters and 5 of them are vowels. They are: E, O, E, I, A. The probability of picking a vowel is 5/11. We could say that there are 5 out of 11 chances of a vowel to occur whenever a piece of paper is taken out of the bag.
470/7= 67.14......
67.14 was her fee
67.14 * 1.5 = 100.71
100.71 is her hourly rate
Is this a multiple choice
Answer:
Step-by-step explanation:
Given
Shape: Opening of a circular vase
Required
Determine the area
This opening implies a circle; hence the area will be calculated using area of a circle.
Solve for radius (r)
Substitute 6.75 for r in
--- Approximated
