Substitute:
Kiera's dance class is 1 hour and 45 minutes long (1:45)
Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres
Well, if you are measuring the area or volume of a figure, then there are different formulas when it comes to spheres, triangles, squares, and etc.
Basically the formulas different, and you need the right formula that goes with that specific shape.
Example: I have a triangle and all its sides are 3 cm. But I only tell you that all my figure's sides are 3 cm. You would need to know the shape of it to do anything worthwhile with that information.
6*5= 30 fingers, so tim would say there are 30 fingers.
