Im literally almost done can someone pls tell me what the surface area formula is for this figure i've missed this time and time again

Step-by-step explanation:

Each circle is pi*r*r (pi r squared)

So 2*pi*r*r

The top of the rectangle if just the circumference of the circle = 2*pi*r

So the area of the rectangle is 2*pi*r*h

So the total area =2*pi*r*r+2*pi*r*h

g

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
