Question

4×22/7×(3.5)^2 show the calculation

Answer 1

Answer=(22/7)*4*3.5*3.5
removing the decimals of both 3.5 ,we get 100 in denominator
(22*4*35*35)/(700)
dividing 700 by 35
(22*4*35)/(20)
dividing 20 by 4
(22*35)/5
dividing 35 by 5
22*7
=154

Answer 2

$\displaystyle \sf{ 4 \times \frac{22}{7} \times {(3.5)}^{2} } = 154$

Given :

The expression

$\displaystyle \sf{ 4 \times \frac{22}{7} \times {(3.5)}^{2} }$

To find :

Simplify the given expression

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

$\displaystyle \sf{ 4 \times \frac{22}{7} \times {(3.5)}^{2} }$

Step 2 of 2 :

Simplify the given expression

$\displaystyle \sf{ 4 \times \frac{22}{7} \times {(3.5)}^{2} }$

$\displaystyle \sf{ = 4 \times \frac{22}{7} \times 3.5 \times 3.5 }$

$\displaystyle \sf{ = 4 \times 22 \times 0.5 \times 3.5 }$

$\displaystyle \sf{ = 88 \times 0.5 \times 3.5 }$

$\displaystyle \sf{ = 44.0 \times 3.5 }$

$\displaystyle \sf{ = 44 \times 3.5 }$

$\displaystyle \sf{ = 154.0 }$

$\displaystyle \sf{ = 154 }$
