Answer:
on what
Step-by-step explanation:
?
10 x 8 = 80ft for the rectangle
To work out the area of the semi circle you do pi (3.14) x the radius squared, the radius is half the diameter.
3.14 x 4 squared
3.14 x16 = 50.24ftsqaured for the whole circle so you divide it by 2 which is 25.12ft squared.
And then finally you add 25.12 and 80 so your answer is 105.12 ft squared
we can see we aren't provided with the perpendicular , so let's find it using Pythagoras Theorem !
<u>substituting</u><u> </u><u>the </u><u>value </u><u>of </u><u>P </u><u>in </u><u>the </u><u>formula</u>
<u>therefore </u><u>,</u><u> </u><u>option </u><u>(</u><u> </u><u>B </u><u>)</u><u> </u><u>is </u><u>correct </u><u>!</u>

Answer:2500 cubic meters (m^3)
Step-by-step explanation:
To find the volume of a rectangular prism (like a pool), use the formula
V = l * w * h
V = 50 * 25 * 2
V = 2500
