Question

Find the value of r^2 = 14 ✖️ 8​

Answer 1

Answer:

$\orange{\mathsf{r = 4\sqrt{7}\:units}}$

Solution:

$\Large{\boxed{\pink{\mathsf{Given\:that:}}}}$

$\green{\mathsf{r^2 = 14 \times 8}}$

$\mathsf{\implies r^2 = 112}$

$\mathsf{\implies r = \sqrt{112}}$

$\mathsf{\implies r = \sqrt{2 \times 56}}$

$\mathsf{\implies r = \sqrt{2 \times 2 \times 28}}$

$\mathsf{\implies r = \sqrt{2 \times 2 \times 2 \times 14}}$

$\mathsf{\implies r = \sqrt{\overline{2 \times 2} \times \overline{2 \times 2} \times 7}}$

$\mathsf{\implies r = 2 \times 2 \sqrt{7}}$

$\mathsf{\implies r = 4\sqrt{7}}$

$\LARGE{\boxed{\gray{\mathsf{r = 4\sqrt{7}\:units}}}}$

Answer 2

Answer:

r^2=112

r=$\sqrt{112}$

r=10.58
