1075 square inches

Formulae:

r = 18.5d = 37C = 116

A = πr2 = π(d2)2

A = C24π

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

Solution Steps:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·18.52 = 1075 square inches(*)

Area of a circle in terms of diameter:

Area = π·(d2)2 = 3.14·(372)2 = 3.14·(18.5)2 = 1075 square inches(*)

Area of a circle in terms of circumference:

Area = C24π = 116.224π = 13502.44(4·3.14) = 13502.4412.56 = 1075 square inches

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
