<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r). Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi). If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>

<h3>Given : </h3>

  • Base of triangle = 8 cm
  • Height of triangle = 4 cm

\\

<h3>To Find : </h3>

  • Area of triangle = ?

\\

<h3>Solution :</h3>

As, we have :

  • Base of triangle, b = 8 cm
  • Height of triangle, h = 4 cm

\\

So, to find area of triangle we have a formula :

\large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}

\tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm

\tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2

\tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2

\tt : \implies Area = 16 \: cm^2

\\

Hence, area of given triangle is 16 cm².

James is buying a table.He finds the same table for sale in two different shops.
mina [271]

"Table World" is quoting a better price

<u>Step-by-step explanation:</u>

The shop "Table World" is quoting a price of 140 inclusive of 17.5% VAT

that means 140 is the final price a customer needs to pay.

                       

While other shop"Tables R us" is quoting a price of 120 without VAT

so we need to add VAT in the price to find out the final price

                                           price+VAT on the price

                                          =120+120*(17.5/100)

                                          =120+120*0.175

                                          =120+21

               so final price      =141

so comparatively "Table World" is quoting a better price
