Answer:

Step-by-step explanation:

Find the area of each shape, then multiply by 20, then round to nearest hundred.

Half circle:

=πr²/2

=50π

=157.08

Large square:

=L•w

=20(22)

=440

Small square:

=L(w)

=12(3)

=36

Triangle:

=b(h)/2

=8(3)/2

=12

Btu req:

=(157.08+440+36+12)(20)

=(645.08)(20)

=12901.6

=12900 BTU

Ayo helppp ill give u anthing

Answer:

16.9 m

Step-by-step explanation:

Start with a half a circle. The central angle of a semicircle is 180 deg.

Now subtract 21 deg on each side.

180 - 21 - 21 = 138

The central angle is 138 deg.

The radius is 7 m.

Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.

$s = \dfrac{n}{360^\circ}2 \pi r$

$s = \dfrac{138^\circ}{360^\circ}2(3.14159)(7~m)$

$s = 16.9~m$
