Answer:
10 cm
Step-by-step explanation:
The volume of the cylinder is 1884 cubic centimetres and its height is 6 cm.
The volume of a cylinder is given as:
where r = radius
h = height
To find the radius of the base of the cylinder, we make r the subject of the formula and solve it:
Divide both sides by πh:
Find the square root of both sides:
Let us find the value of r:
=> r = 9.9975 cm ≅ 10 cm
Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430

First u divide 39.39 to 3 and u get 13.13 so it is already rounded u dont need to round<span />
