Answer:
h≈6.93 units
Step-by-step explanation:
To find the height of a cone with radius 2 units and volume of 29 cubic unit, we will follow the steps below;
first, write down the formula for finding the volume of a cone;
v=πr²
where v is the volume of the cone
r is the radius of the cone and
h is the height of the cone
From the question given, radius r = 2 units and volume v = 29 units³
π = 3.14
We can now proceed to insert the values into the formula and then solve for h
v=πr²
29 = 3.14 × 2² ×
29= 3.14 × 4 ×
29= 12.56 ×
29 =
Multiply both-side of the equation by 3
29 × 3 = × 3
At the right-hand side of the equation 3 will cancel-out 3
87 = 12.56 h
Divide both-side of the equation by 12.56
87/12.56 = 12.56 h /12.56
At the right-hand side of the equation 12.56 will cancel-out 12.56 leaving us with just h while on the left-hand side of the equation 87 will be divided by 12.56
6.926756 = h
h = 6.926756
h≈ 6.93 to the nearest hundredth
h≈6.93 units
