What the answer plss

To find the circumference, you multiply the radius by 2 and then multiply that by pi (or π). The equation is 2πr

In this case, we already have the radius x 2, which is the diameter. For this circle, the diameter is 12 cm.

The next step is to multiply the diameter, 12 cm, by pi (π is about equal to 3.14)

12 x π ≈ 37.698 cm or 38 cm rounded to the nearest whole number

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
