Dogs are a very faithful animal. It has a sharp mind and a strong sense of hearing smelling the things.
I'm pretty sure the answer is b. because obviously 1.2 in is the least and the second least is the square root of 3.
4.44 because 40 divided by 9 is 4.44
The correct answer is D. You can solve this by multiplying the values.
Surface area is defined as the sum of all the areas covers the object so here we have 2 cylinders and the
Area of a cylinder = side area + area of the circle
side area = <span>perimeter * height = 2*pi* r *h
</span>area of the circle = pi * r^2
for the cylinder, we have 2 area circle and 1 side area
so surface area = 2 *pi * r*h + 2 pi* r^2
so for the first cylinder
A1 = 2*pi*r*h +2 pi * r^2 = (2*pi * 2 *2) +( 2 *pi * 2^2 ) = 16pi inch^2
A2 = 2*pi*r*h + 2pi *r^2 = ( 2 * pi * 1.25*3)+( 2*pi *(1.25)^2) = 85/8 pi inch^2
A= A1 +A2
A = 16pi + 85/8 pi = 83.645 inch^2
