22/7 × 21 × 21 ×10,5 =tolong di jawab ya kak…

$sf frac{22}{7} times 21 times 21 times 10.5$

$sf = frac{1.386}{1} times 10.5$

$sf = frac{1.386}{1} times 10 frac{5}{10}$

$sf = frac{1.386}{1} times frac{10 times 10 + 5}{10}$

$sf = frac{1.386}{1} times frac{105}{10}$

$sf = frac{1.386}{1} times frac{105 div 5}{10 div 5}$

$sf = frac{1.386}{1} times frac{21}{2}$

$sf = frac{1.386 times 21}{1 times 2}$

$sf = frac{29.106}{2}$

$sf = frac{29.106 div 2}{2 div 2}$

$sf = frac{14.553}{1}$

$sf = 14.553$
