Solve r=9.8/4(3.14)^2(0.028)^2

$$r = \frac { 9.8 } { 4 ( 3.14 ) ^ { 2 } ( 0.028 ) ^ { 2 } }$$

Solve for r

$$r = \frac{7812500}{24649} = 316\frac{23416}{24649} \approx 316.949977687$$

Steps for Solving Linear Equation

Calculate 3.14 to the power of 2 and get 9.8596.

$$r=\frac{9.8}{4\times 9.8596\times 0.028^{2}}$$

Multiply 4 and 9.8596 to get 39.4384.

$$r=\frac{9.8}{39.4384\times 0.028^{2}}$$

Calculate 0.028 to the power of 2 and get 0.000784.

$$r=\frac{9.8}{39.4384\times 0.000784}$$

Multiply 39.4384 and 0.000784 to get 0.0309197056.

$$r=\frac{9.8}{0.0309197056}$$

Expand \frac{9.8}{0.0309197056} by multiplying both numerator and the denominator by 10000000000.

$$r=\frac{98000000000}{309197056}$$

Reduce the fraction \frac{98000000000}{309197056} to lowest terms by extracting and canceling out 12544.

$$r=\frac{7812500}{24649}$$

Assign r

$$r≔\frac{7812500}{24649}$$
