Number four is 8.0596 and number 5 is 1.98102
a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2
I hope this helps you
Area=width×length
161=width×14
width=161/14
width =11,5
2 chocolate chip: 3 sugar So, this is the ratio.
The sum of this is 5 but we need it to be 20, because there are 20 cookies.
Let's try multiplying 4 to each side:
4 * 2 chocolate chip : 4 * 3 sugar
8 chocolate chip: 12 sugar
8 + 12 = 20
So, you have 12 sugar cookies.
Final Answer: 12 sugar cookies
That's a good question. When comparing negative numbers the lower one has a greater 'number part ( without the sign)' then the higher one.
For example -4 and -10:- 10 > 4 but -4 > -10.
