Change to an improper fraction 4 2/3=

Answers

Solutions 

To solve the problem the first step is to multiply the whole number by the fraction's denominator (4 x 3).Add the numerator (2) to the product. 

4 * 3 = 12 

12 + 2 = 14 

= 14/3 
First multiply the denominator by the whole number.
3*4=12
Now add the numerator.
12+2=14
14 is the numerator,  denominator stays the same.
You answer is 14/3!

If a semi circle has a diameter of 5 m what is the area?

Answers

Answer:

Exact answer = 10.41666666666666666666666666666pi

Estimated answer = 32.70938

Step-by-step explanation:

Semi circle formula: 1/2 * 4/3 * pi * r^3

r = 2.5

1/2 * 4/3 * pi * 2.5^3

2/3 * pi * 2.5^3

2/3 * pi * 15.625

10.416..... * pi

Exact answer = 10.417pi

We can estimate pi as 3.14

So, 10.417 * 3.14 = 32.70938

Exact answer = 10.41666666666666666666666666666pi

Estimated answer = 32.70938

The circumference of a pizza is 75.36 in. What is the approximate area of the circle? Answers A.(113.04 in2)
B.(37.68 in2)
C.(1808.64 in2)
D.(452.16 in2)

Answers

Circumference = diameter x pi

Find the diameter:

75.36 = diameter x pi

Divide both sides by pi:

Diameter = 75.36/3.14 = 24 inches.

Area = pi x r^2

R = 1/2 diameter = 12

Area = 3.14 x 12^2

Area = 452.16 in^2

The answer is D.
