2. FIND THE TOTAL AREA OF THE OUTSIDE SURFSCE OF A CYLINDER 54CM IN DIAMETER AND 75 IN HEIGHT.
3. FIND THE VOLUME OF A RECTANGLE SOILD 6.9 M LONG 1.8 M WIDE AND 4.7M HIGH
4. VOLUME OF A CYLINDER WITH A DIAMETER 70FT AND A HEIGHT OF 46FT
5. FIND THE VOLUME OF A CONE 14IN IN DIAMETER AND 10 IN HIGH
6. WHAT IS THE VOLUME OF A SPHERE WHOSE DIAMETER IS 84 CM

THANKS FOR ALL YOU HELP

I think you might know the formulas to solve these problems...ANy way if you dont have them .. i am giving them now and try to substitute the values for yourself and solve them which only helps you .. we can solve them for you ... but we want you to solve them for yourself ... you just need to substitute the values and know for yourself...
1) circumference of circle : 2**r = d* as r = 2d
here r = radii and d = diameter, pi= 3.14

2)Surface area of cylinder : 2 ** r* h + 2**
2**r(r+h) = d*(2*d + h)
where r = radii and h = height and d = diameter,pi = 3.14

3)Volume of cubeoid = x*y*z where x,y and z are the dimensions of the cubeoid

4) volume of cylinder = **h
=**h
=**h

where r = radii and h = height and d = diameter (2*radius),pi = 3.14

5) Volume of cone = =
where h = height of the cone,d = diameter of cone,r = radius,pi = 3.14

6) volume of sphere:=
where pi= 3.14 and d = diameter
