How should the following statement be written in if - then form?

the sum of the measures of the angles of a triangle is 180 degrees.

if the sum of the measures of the angles is 180 degrees, then there exists a triangle.
if a triangle exists, then the sum of the measures of the angles is 180 degrees.
if two rays are opposite, then they form a straight line.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857
