HELPP MEE!!! Find the total area of the figure below. Round your answer to the nearest tenth.

timama [110]

Answer:

area = 110.72 m²

Step-by-step explanation:

area of square = 8 x 9 = 72 m²

area of triangle = 1/2 x 3 x 9 = 13.6 m²

area of semi circle = 1/2πr² = 1/2(3.14)(4²) = 25.12 m²

total area = 72 + 13.6 + 25.12 = 110.72 m²

About how accurately must the tank's exterior diameter be measured to calculate the amount of paint it will take to paint the si

kondaur [170]

Answer: The error of the diameter would be 5% .

Step-by-step explanation:

Since we have given that

$S=2\pi rh$

Here, r is the radius

h is the height

So, it becomes,

$S=2\pi (\dfrac{D}{2})h\\\\S=\pi Dh\\\\S=\pi D\times 10\\\\S=10\pi D$

So, we will derivate S wrt D, we get that

$\dfrac{dS}{dD}=10\pi\\\\dS=10\pi dD$ ---------------------(1)

As we have given that

it will take to paint the side of the tank to within 5% of the true amount.

So, it becomes,

$dS=0.5\pi D$ ---------------(2)

So, from (1) and (2) , we get that

$0.5\pi D=10\pi dD\\\\\dfrac{0.5\pi}{10\pi}=\dfrac{dD}{D}\\\\0.05=\dfrac{dD}{D}=5\%$

Hence, the error of the diameter would be 5% .
