Pls help this is major, ill mark u brainliest
Lera25 [3.4K]

Answer:

105

Step-by-step explanation:

A=lw   A=(.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

A=(16)(9)

A=144

A=\frac{(3.14)(5)^2}{2} A=\frac{(3.14)(25)}{2} A=\frac{78.5}{2}

A=39.25

subtract the areas

144-39.25=104.75

104.75 ≅ 105

Could anyone help me with this problem i'm stuck <br><br> h(17)= ?
nikdorinn [45]

Answer:

\sqrt{17t}

Step-by-step explanation:

Consider the right side of the table

It informs us of the values for h(t) for different values of t

The top one informs us what h(t) is when t = 17, that is

h(t) = \sqrt{17t}, when t = 17, thus

h(17) = \sqrt{17t}
