Answer:
h = 6 cm
Step-by-step explanation:
Volume of cylinder = 54 π cm³
πr²h = 54π
π * 3 * 3 * h = 54π
The sum of an angle and its complement =90°
The angle is 59°; its complement is 31°
Step-by-step explanation:
Given measure of an angle is 28 degrees greater than its complement.
By definition the sum of an angle and its complement =90°
Let the angle be x
The angle's complement must be x−28° (from the given information)
x+(x−28°)=90° or
2x= 118° or
x= 59° or
So the angle is 59° and its complement is 59°−28°=31°
Answer:
h = 22.91 cm
Step-by-step explanation:
Given that,
The volume of a vase, A = 1330.2 cm³
Radius of the vase, r = 4.3 cm
We need to find the height of the vase. The formula for the volume of a cylinder is given by :
or
h = 23 cm
So, the height of the vase is equal to 23 cm.
Answer:
1/8
Step-by-step explanation:
One half of the cake is four slices, and the entire cake (if it was all there) would be 8 slices. For the four slices to be distributed equally among the four people, each person gets 1 slice. 1 slice out of the 8 total in the cake would be 1/8 of the whole.
