Answer:
a) 94.2 cm
b) 78.5%
Step-by-step explanation:
a) since the square side = 30 cm
it means the diameter = 30 cm
then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm
b) the perimeter of the square = 30×4 = 120
94.2 for 120
x% for 100%
x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%
The answer is B: 6 cm. You can use guess-and-check method, and plug the possible different answers into the equation x(x+6)=72, x stands for the width.
Answer:
4.71, 4.72, 4.73, 4.74, 4.75, 4.76,4.77, 4.78, and 4.79
Step-by-step explanation:
all you need to do is move into hundredths and you need to know that there are 10 hundredths between 2 tenths.
Supplementary and adjacent.
Two angles are called supplementary when their measures add up to 180 degrees.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap.
I think the area of this triangle is 27.1 square cm. Hope it help!
