Question

The cylinder shown below has a radius of 3 inches and a height of 23 inches.



What is the approximate lateral area of the cylinder? Use for pi.

433.71 in2

490.29 in2

462.00 in2

216.86 in2

Answer 1

by lateral did you mean "outside"?
sorry, i cant see the picture

Answer 2

If you mean the surface area, the answer is:
2x Area of Base + area of rectangle
=2x (pi x r^2) + (2 x pi x r x ht)

Answer 3

HERE LATERAL SURFACE AREA IS CURVED SURFACE AREA = 2*PI*R*H
= 2 *3.14*3*23 = 433 INCHES (APPROX)

Answer 4

thanks so much !!!
