Step-by-step explanation:
The area of a circle = pi r^2
d = 2r Divide by 2 to get the radius
r = d/2
The diameter = 2.8 cm
r = d/2
r = 2.8/2
r = 1.4
The area of the circle = pi * r^1
The area of the circle = 3.14 * 1.4^2
The area of the circle = 6.1544
But you are working with a semic circle
The area of a semicircle is 1/2 that of a circle
Area of semicircle = 1/2 6.1544 = 3.0772 =3.08 when rounded
Answer: The large ____ holds 48 units.
For the diagram you could draw the small rectangle 4 squares wide and 9 squares long. that will represent something that holds 36 units.
For the large one make it 4 squares wide and 12 squares long. That will have spaces for 48 units.
Step-by-step explanation: Change the percent to a decimal and set up the equation that means 36 is 75% of some number, yet unknown, X is the unknown number.
36 = .75x divide both sides by .75
36/.75 = .75x/.75 . The .75 "cancels" on the right. Then use a calculator.
36 ÷ .75 = 48
x = 48
