If the semicircle is on the 29 side:
<span>2(19) + 29 + 29pi/2 = 67 + 14.5pi </span>
<span>This is because the radius is equal to 1/2 the diameter and the perimeter of a semicircle is radius*pi. The 2 19's come from the rectangle part of the garden and the other 29 comes from the side opposite the semicircle. </span>
<span>If the semicircle is on the 19 side: </span>
<span>2(29) + 19 + 19pi/2 = 77 + 9.5pi </span>
<span>You simply switch the 19 and 29 values.</span>

A. Moho barrier </span>The Moho<span> is the boundary between the crust and the mantle in the earth.
</span><span>B. Oceanic crust
</span>is the uppermost layer of the oceanic portion of a tectonic plate. The crust overlies the solidified and uppermost layer of the mantle. The crust and the solid mantle layer together constitute oceanic
<span>Lower mantle
</span>A large fraction of Earth's interior, from a depth of about 650 km (400 miles) down to 2,900 km (1,800 miles), consists of the lower mantle, which is composed chiefly of magnesium- and iron-bearing silicates, including the high-pressure equivalents of olivine and pyroxene.
<span>upper mantle
</span>The upper mantle<span> begins just beneath the crust and ends at the lower mantle.

hope this helps you(:
if not plz let me know(;
According to the theory, the Earth's crust is made up of continental and oceanic plates, which move across the surface of the planet, meeting at plate boundaries. Plate tectonics cause volcanic activity, mountain-building, ocean trench formation and earthquakes.
<span>Five strategies needed by learners in taking </span><span>appropriate actions for availability of clean water maybe the ff:
(1) conserve water by turning off the faucet when unused;
(2) research more on how to conserve water
(3) use social media to spread awareness of conservation of water
(4) innovate ideas on conservation of water
(5) make machines that can filter water's impurities</span>
