Joanna plans on hanging 3 pictures of different sizes on the wall of her staircase. she thinks it will look best if all 3 rectangular pictures are similar. the two sizes she has already are 25 in. by 35 in. and 35 in. by 49 in. which of the following is a possible size of the third picture?
a.
5 in. by 6 in.
b.
30 in. by 42 in.
c.
45 in. by 70 in.
d.
50 in. by 63 in.

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

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
