18 = 2×3×3

30 = 2×3×5

The LCM will have factors of 2, 3², and 5. (Choose the highest power of each prime.)

2×3×3×5 = 90 is the LCM of 18 and 30.

Explain how you got the answer please
Alisiya [41]
The answer is C.
You want:

10 < a < 14  (greater or equal)
The difference between 10 and 12 is 2.
The difference between 12 and 14 is 2.
Therefore the absolute value allows you to express that the difference between a and 12 cannot be greater than 2 (either going up to a max of 14 or going down to a minimum of 10).

Explain how to find the surface area of a can of fruit with a height of 80 mm and a diameter of 60 mm. Give the area in your exp
8_murik_8 [283]

Answer:

S=6600\pi \text{ mm}^2

S\approx 20724 \text{ mm}^2

Step-by-step explanation:

A can of fruit is geometrically a cylinder.

We are talking about the <u>surface area of a cylinder</u>:

S=2\pi rh+2\pi r^2

\pi \approx 3.14

r: \text{radius}

h: \text{height}

Factoring, we have:

S=2\pi r (h+r)

Calculating the surface area of the can of fruit:

S=2\pi (30) (80+30)

S=2\pi (30) (110)

S=6600\pi

S\approx 20724 \text{ mm}^2
