An equilateral triangle has an apothem measuring 2. 16 cm and a perimeter of 22. 45 cm. An equilateral triangle has an apothem with length 2. 16 centimeters and a perimeter of 22. 45 centimeters. What is the area of the equilateral triangle, rounded to the nearest tenth? 2. 7 cm2 4. 1 cm2 16. 2 cm2 24. 2 cm2.

the answer is a

step-by-step explanation:

i think that you should ask google for the answer to that problem because if we don't know it google does

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
