Answer:

V = 37.7cm^3

Step-by-step explanation:

The formula for the volume of a cone is:

V = \frac{1}{3} \pi r^2h

Given:

- Radius = 2cm

- Height = 9cm

Let's plug these into the equation:

V = \frac{1}{3} \pi (2)^2(9)

Now solve:

V = \frac{1}{3} \pi (4)(9)\\V = \frac{1}{3}\pi 36\\V = \frac{36}{3}  \pi \\V = 12\pi \\V = 37.7cm^3

Therefore, the volume of the cone is 37.7cm^3.

Which subtraction expression
Bond [772]
If you would like to know which subtraction expression has the difference 1 + 4i, you can calculate this using the following steps:

a. (–2 + 6i) – (1 – 2i) = –2 + 6i – 1 + 2i =  –3 + 8i

b. (–2 + 6i) – (–1 – 2i) = <span>–2 + 6i + 1 + 2i =  </span>–1 + 8i

c. (3 + 5i) – (2 – i) = 3 + 5i – 2 + i = 1 + 6i

d. (3 + 5i) – (2 + i) = 3 + 5i – 2 – i = 1 + 4i

The correct result would be <span>d. (3 + 5i) – (2 + i).</span>

If the width of something is 5m and the perimeter is 22m, what is the length and area
Nadusha1986 [10]
I assume that this 'something' has a rectangular shape. If its width is 5m, than the length of two sides is 2 * 5 = 10m. Now if the perimeter is 22 square meters, then the lenght of another two sides is 12 / 2 = 6.

12 because 22 (the perimeter) - 10 (lenght of the 2 sides) = 12 (length of another 2 sides).

. The new saleswoman at Clocks Unlimited was very good. During her first day on the job she sold at least two of each of the thr
LiRa [457]

Answer:

5

Step-by-step explanation:

Let the number of the kitchen clock sold =a

Let the number of the cuckoo clock sold =b

Let the number of the two-foot high grandfather clocks sold =c

The new saleswoman sold at least two of each of the three models.

Therefore:

a\geq 2\\b \geq 2\\c \geq 2

In all, she collected $300 from selling these models alone

17a+31b+61c=300

17(2)+31(2)+61(2)=218

300-218=82

Next, we try to express the remainder (82) in terms of 17, 31 and 61

82=17(3)+31

Therefore, she sold:

  • 5 kitchen clocks
  • 3 cuckoo clocks
  • 2 two-foot high grandfather clocks

She sold 5 $17 clocks.

CHECK:

17(5)+31(3)+2(61)=$300
