Answer:
Step-by-step explanation:
4x+2/3=31/2
move constant to the right
4x=31/2-2/3
subtract the fractions
4x=89/6
divide both sides by 4
x=89/24
x=3.708
area of circle = pi r squared
diameter is 63cm
then radius is 63/2, or 31.5cm
3.14*31.5^2= 3115.665cm squared
3115.665 is the area of the whole circle, divide that by two to get the area of the semicircle
so 3115.665/2 = 1557.8325 cm squared
1557.8325 rounded to two decimal points is 1557.83cm squared
1557.83cm squared is the area of the semi circle
hope that helped! :)
To convert gallons to pints, multiply the gallons by 8. Since there are 4 quarts in a gallon and 2 pints in each quart, you multiply by 8 since 4*2 is 8.
7×10^7 = 70000000 (10^7 = 10000000)
