- What is the area of the figure below? Use 3.14 for T. 7 cm 22 cm 18 cm

ziro4ka [17]

Answer: $\Large\boxed{Total~area=586.17~cm^2}$

Step-by-step explanation:

<h2>PART I: Find the area of the triangle</h2>

Given information

$Height=7~cm$

$Base=18~cm$

Given formula

$A=b\times h\times\dfrac{1}{2}$

$A=Area\\b=base\\h=height\\$

Substitute values into the formula

$A=(7)\times (18)\times\dfrac{1}{2}$

Simplify by multiplication

$A=(7)\times 9$

$A=63~cm^2$

<h2>PART II: Find the area of the rectangle</h2>

Given information

$Height = 18~cm$

$Base=22~cm$

Given formula

$A=b\times h$

$A=Area\\b=base\\h=height\\$

Substitute values into the formula

$A=(22)\times (18)$

Simplify by multiplication

$A=396~cm^2$

<h2>PART III: Find the area of the half-circle</h2>

Given information

Diameter = 18 cm

Given formula

$A=(\dfrac{d}{2} )^2\times \pi \div2$

$A=Area\\d=diameter$

Substitute values into the formula

$A=(\dfrac{18}{2} )^2\times (3.14) \div2$

Simplify the fraction

$A=(9 )^2\times (3.14) \div2$

Simplify the exponents

$A=81\times (3.14) \div2$

Simplify by multiplication

$A=254.34\div2$

Simplify by division

$A=127.17~cm^2$

<h2>PART IV: Find the total area</h2>

Given formula

$Total~area=Triangle+Rectangle+circle~(half)$

Substitute values into the formula

$Total~area=(63)+(396)+(127.17)$

Simplify by addition

$Total~area=459+(127.17)$

$\Large\boxed{Total~area=586.17~cm^2}$

Hope this helps!! :)

Andy is one fourth as old as his grandfather who is 76 years old write an equation to determine whether Andy is 19 or 22 years o

iren [92.7K]

76÷4= ; x=19, you divide 76 by 4 because if he is 1/4 then it would be a group of one of the 4's, thus saying ehen you divide 76 by 4, it equals 19, so he is 19 years old, you could also do 19×4 and 22×4 to see which equals 76.
