Solve 3.14*(0.72)^2*y=2.8

$$3.14 \times ( 0.72 ) ^ { 2 } \times y = 2.8$$

Solve for y

$$y = \frac{21875}{12717} = 1\frac{9158}{12717} \approx 1.720138397$$

Steps for Solving Linear Equation

Calculate 0.72 to the power of 2 and get 0.5184.

$$3.14\times 0.5184y=2.8$$

Multiply 3.14 and 0.5184 to get 1.627776.

$$1.627776y=2.8$$

Divide both sides by 1.627776.

$$y=\frac{2.8}{1.627776}$$

Expand \frac{2.8}{1.627776} by multiplying both numerator and the denominator by 1000000.

$$y=\frac{2800000}{1627776}$$

Reduce the fraction \frac{2800000}{1627776} to lowest terms by extracting and canceling out 128.

$$y=\frac{21875}{12717}$$
