I think it’s the first answer AB and CD
4x = 28
28 divided by 4 = 7
x = 7
4•7=28 (TRUE STATEMENT)
412 divide by 84 how many times can 84 go into 412
84 can go into 412, 4 times and four time 84 equals
331, then continue dividing 84 into the number you obtain by sutracting the number before and the multiple of 84 and x
your answer will be 4.904
1. Area of a circle is pi x R^2
Area = 3.14 x 18^2
Area = 3.14 x 324= 1017.36 sq. In.
The blade covers 122 out of 360 degrees.
1017.36 x 122/360 = 345 square inches.
2.
Like above.
Area =3.14 x 75^2 = 17,662.5 square feet
17662.5 x 80/360 = 3,925 square feet.
