Answer:
Answer:
h = \frac{2A}{b}
Step-by-step explanation:
Given
A = \frac{1}{2} bh
Multiply both sides by 2 to clear the fraction
2A = bh ( isolate h by dividing both sides by b )
h = \frac{2A}{b}
Answer:
A) -2
Step-by-step explanation:
Plus 4 in place of x
f(x) = -3x+10
f(4) = -3*4+10
f(4) =-12+10
f(4)=-2
Answer:
C. 134.04
Step-by-step explanation:
The formula to calculate the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height</em>
<em />
The base of the cone is a circle, so that the formula to calculate the are of the base is: <em>Area of base = </em> x
The radius of the base is 4cm
=> <em>Area of base = </em> x 4^2 = 3.14 x 16 = 16
The height of the cone is given equal to 8 cm
So the volume of the cone is:
+) <em>Volume of a cone = 1/3 x Area of base x Height = 1/3 x 16</em><em> x 8 = 134.04 </em><em />
<em />
So the answer is C
