To find the value of x , bring the variable to the left side and bring all the remaining values to the right side. simplify the values to find the result.
We find the value for s here.
8s = 1/2
1/2 divided by 8/1 = 1/2 * 1/8 = 1/16
s = 1/16
Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
Answer:
21
Step-by-step explanation:
Of means multiply and since we want an estimate we can round 72 to 70
30% * 70
.30 * 70
21
