valkas [14]

Answer:

Option E

Step-by-step explanation:

The standard equation of circle is:- (x-h)² + (y-k)² = r²

where (h,k) is center point and r is radius

If radius r is decreased then also (h,k) remains same, only r² increases

Equation given in question is x² + y² + Cx + Dx + E=0

So, C and D will remain same but E will increase

levacccp [35]

Answer:

2(25)^{\dfrac{1}{3}}

Step-by-step explanation:

The volume of a cube is 200 cm².

We need to find the edge length of the cube.

The formula for the volume of a cube is given by :

V=a^3

a is the side of the cube

a=\sqrt[3]{200} \\\\=(200)^{\dfrac{1}{3}}\\\\=(25\times 8)^{\dfrac{1}{3}}\\\\=(25)^{\dfrac{1}{3}}\times (8)^{\dfrac{1}{3}}\\\\=2(25)^{\dfrac{1}{3}}

So, the edge length of the cube is 2(25)^{\dfrac{1}{3}}.

Vikentia [17]

Answer:

Volume of the rectangular prism=369cm^3

Step-by-step explanation:

Length=2\frac{1}{4} =\frac{9}{4} cm\\\\Width=8cm\\\\Height=20\frac{1}{2} =\frac{41}{2}cm

Volume of a rectangular prism = Length*Width*Height

                             =\frac{9}{4}*8*\frac{41}{2}\\\\  =\frac{72}{4}*\frac{41}{2}  \\\\=18*20.5\\\\=369cm^3

The volume of the rectangular prism with the given dimensions is 369cm^3
