Use Heron's Area Formula to find the area of the triangle.
a = 39,
b = 30, c = 25

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

the answer is 62.8 cubic units

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
