Answer:
102in2
Step-by-step explanation:
The formula for surface area is 2(wl+hl+hw). So plug in the measurements of the prism into the formula to get 102.
Please, use the symbol " ^ " to denote exponentiation. At first I had no idea what you meant by 3r2.
You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches. Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).
Answer:
5(a-b)=3(a+b)
5a-5b=3a+3b
2a-2b=0
2a=2b
a=b
a:b=1
Step-by-step explanation:
Length is equal to 4 and width is equal to 5.
You can just divide each by 2.
