SA = 2\pi rh+2\pir^2

1. Find the radius.

R = 1/2D

6 x 1/2 = 3

R = 3

2. Plug them in.

SA 2(3.14)(3)(7) + 2(3.14)(3^2)

3. Solve

3 x 7 = 21

21 x 3.14 = 65.94

65.94 x 2 = 131. 88

3^2 = 9

9 x 3.14 = 28.26

28.26 x 2 = 56.52

4. Add them together.

131.88 + 56.52 = 188.4

Answer: 188.4 square millimeters

A crayon has a mass of 30 grams. How many crayons can be made with 30 kilograms of colored wax
PolarNik [594]
The conversion factor between kilo and base unit which is grams in this question is 1000 so there is 1000 grams in 1 kilogram so first we need to convert kilograms to grams so we multiply by 1000 so 30kgx1000= 30000 grams so to find the number of crayons then we divide by 30 which is the mass of one crayon to find out how many we need so 30000/30= 1000 so you would need 1000 crayons

Help ASAP <br> I don’t really understand this question
german
It’s C. ( 3 . -5 ), because the you want to look at where the two lines intersect. So you want to always look at the X - Axis first. And that’s on the 3. Now you want to look at the Y - Axis. And that’s on - 5. So you answer will be C. ( 3 . -5 )

Line I has a slope of 13/7. The line through which of the following pair
ivolga24 [154]

Answer:

Step-by-step explanation:

You need to find the set of points that will yield a slope that is the negative reciprocal of the slope of Line L because perpendicular lines have negative reciprocal slopes. The negative reciprocal of 13/7 is -7/13. Which set of points will produce this result? The formula for finding the slope is:

m = (y2 - y1)/(x2 - x1)

Consider the second set of coordinates.

(2 - (-5))/(-7 - 6) = (2 + 5)/(-13) = -7/13

The second set of coordinates satisfy the condition.
