Explanation:
The rectangle can have the dimensions 2cm and 4cm.
The area of a rectangle is length times width. 2cm X 4cm = 8cm²
Basically there asking you is correct or incorrect of his answer if Yes explain if NO also explain why :) hope I helped
Radius = 15/2 = 7.5
Volume of cone: pi(r)^2*h/2
= pi(7.5)^2*23/2
pi(56.25) * 23/2
(3.14)(56.25)(23)/2 = 2,031 inches
Step-by-step explanation:
as we can see that the sides are in the ratio of 2:1 and are consecutive
so
a;b=2:1
a=4
b=8
