Solve pi8^2-pi6^2/pi10^2

$$\frac{ \pi { 8 }^{ 2 } - \pi { 6 }^{ 2 } }{ \pi { 10 }^{ 2 } }$$

Evaluate

$$\frac{7}{25}=0.28$$

Solution Steps

Calculate 8 to the power of 2 and get 64.

$$\frac{\pi \times 64-\pi \times 6^{2}}{\pi \times 10^{2}}$$

Calculate 6 to the power of 2 and get 36.

$$\frac{\pi \times 64-\pi \times 36}{\pi \times 10^{2}}$$

Combine \pi \times 64 and -\pi \times 36 to get 28\pi .

$$\frac{28\pi }{\pi \times 10^{2}}$$

Calculate 10 to the power of 2 and get 100.

$$\frac{28\pi }{\pi \times 100}$$

Cancel out 4\pi in both numerator and denominator.

$$\frac{7}{25}$$

Factor

$$\frac{7}{5 ^ {2}} = 0.28$$
