Answer:
9 square inches is your answer. √9=3
For the first question asking about the slope 3/4 and y intercept -2 would be (y=0.75x-2) because 3/4=0.75 and the y intercept -2 is b and you’re just placing it into the formula y=Mx+b m=slope b=y intercept.
Answer:
9
Step-by-step explanation:
Good ol' PEMDAS
First things first, we simplify what is in the parentheses.
4/2 ÷ 2 + (3² - 1)
4/2 ÷ 2 + (9 - 1)
4/2 ÷ 2 + 8
Next we do division. Because there are two instances of division, we work left-to-right. Note that a fraction such as 4/2 is division itself.
4/2 ÷ 2 + 8
2 ÷ 2 + 8
1 + 8
Lastly, it just solving the addition.
1 + 8 = 9
We know that
volume of a cone=(1/3)*pi*r²*h
<span>If the height of a cone is cut in half
so
h=h/2
and
new volume of a cone=</span>(1/3)*pi*r²*(h/2)----> (1/2)*[(1/3)*pi*r²*h)
the answer is
<span>the volume of the cone is multiplied by 1/2</span>
