a composite figure is made up of a rectangular prism sandwiched between two halves of a cylinder. which of the following surface area equations could you use to find the total surface area of the solid?

SA = 2lw + 2lh + 2wh

SA =2πrh+ 2πr2

Step-by-step explanation:

Hi, to find the total surface of the solid we have to sum the surface area of each of the different solid parts that made up the total solid.

So, we have a rectangular prism

Surface area of a rectangular prism: A = 2wl + 2lh + 2hw,

Where:

w = width

l= Length

H= height

And 2 halves of a cylinder. 2 halves of a cylinder are equal to a full cylinder so:

Surface area of a cylinder = 2πrh+ 2πr2  

Where r is the radius

So, the correct options are:

SA = 2lw + 2lh + 2wh

SA =2πrh+ 2πr2

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
