Hi guyys helppp!

The diameter of DNA is about 20 Angstrom. Express the surface area of the molecule in m^2 and in^2. (A=pi d^2) 1A= 1x10^-10; 1m=39.37 in.

The area of a circle=RADIUS^2 x PI

Area in square meters=3.14159265358 x 10^-38 square meters

Area in square inches =4.864518144 x 10^-35 square inches
