Answer:
The surface area is 3317.52 inch^2
Step-by-step explanation:
The drum is in the shape of a cylinder, therefore..
Area of the drum
=2πrh+2πr^2
=2*π*12*32+2·π*12^2
= 3317.52 inch^2
Answer:
Step-by-step explanation:
Deal #1: One pizza= $8.99
Deal #2: One pizza= $6.00
Deal #1: Two pizzas= $13.99
Deal #2: Two pizzas= $12.00
Deal #1: Three pizzas= $18.99
Deal #2: Three pizzas= $18.00
Deal #1: Four pizzas= $23.99
Deal #2: Four pizzas= $24.00
Therefore, after FOUR pizzas, deal #1 becomes a better deal.
Tip: Practice some math. You should be able to answer something like this within two minutes MAXIMUM.
Answer:
A ≈ 530 cm²
Step-by-step explanation:
The swept area equals the total area covered by the blade minus the unswept area.
The area of a sector with radius r and angle θ is:
A = (θ / 360) πr²
So the swept area is:
A = (θ / 360) πR² − (θ / 360) πr²
A = (θ / 360) π (R² − r²)
A = (150 / 360) π (21² − 6²)
A ≈ 530 cm²
Answer: OPTION C
Given the functions shown in the figure attached, you have that f(x)*g(x), means that you must multiply both functions.
Therefore, you have:

Now, you must apply the distributive property, therefore, you obtain:

As you can see, the answer is the Option C.
Answer:
= .0000001
Step-by-step explanation:
The odds of getting 1 number of out the 10 possible number (0-9) equal 10 is 1/10
There are 7 numbers to pick
P(xxx-xxxx) = 1/10 * 1/10 *1/10 * 1/10 * 1/10 * 1/10 *1/10
= .0000001
