Area of circle: pi * r^2
Given: pi = 3.14, r = 5
Area: 3.14 * 5^2
3.14 * 25 = 78.5
Solution: 78.5 square units
Surface area=2A + BH
where A is the area of the base, B the perimeter of the base and H the height.
S.A=2*4.5*6 +2(4.5+6)*12
S.A=54+252
S.A= 306 sq. inches
It would b 5 !!!!!!!!!!!!!!!!!!!!
Let's think:
1 ton ------------ 1000 kilograms
3.2 tons ----------- x kilograms
Multiply in cross
1 . x = 1000 . 3.2
x = 3200
So 3.2t = 3200 kilograms
36*1000m/1h =a
a/3600 to get seconds
