Cone A has a radius of 2 inches and a height of 3 inches. In cone B, the height is the same, but the radius is doubled. Calculat

wlad13 [49]

Answer: Option C.

Step-by-step explanation:

Use the formula for calculate the volume of a cone:

$V=\frac{1}{3}\pi r^2h$

Where r is the radius and h is the height.

Volume of the cone A:

$V_A=\frac{1}{3}\pi (2in)^2(3in)=12.56in^3$

Volume of the cone B:

If the height of the cone B and the height of the cone A are the same , but the radius of the cone B is doubled, then its radius is:

$r_B=2r_A\\r_B=2*2in\\r_B=4in$

Then:

$V_B=\frac{1}{3}\pi (4in)^2(3in)=50.26in^3$

Divide $V_B$ by $V_A$ :

$\frac{V_B}{V_A}=\frac{50.26in^3}{12.56in^3}=4$

Therefore: When the radius is doubled, the resulting volume is 4 times that of the original cone.

The equation of a circle is given below. x ^2 +(y-2.25)^2 =196/169. What is the center? What is the radius?

yuradex [85]

Answer:

center : (0, 2.25)

radius: 14/13

Step-by-step explanation:

x^2+(y-2.25)^2=196/169

Rewrite x^2+(y-2.25)^2=196/169

(x-0)^2+(y-2.25)^2=(14/13)^2

c=(0,2.25),r= (14/13)

A 16 by 18 foot rectangular section of a wall will be covered by square tiles that measure 2 feet on each side. If the tiles are

34kurt

Answer:72 tiles

Step-by-step explanation:

16 x 18 = 288ft.2

2 x 2 = 4ft.2

288 divided by 4 = 72 tiles

Since 288 is the space of the wall, each tile has an area of 4 feet squared, so 288 divided by 4 would make it so they need 72 tiles.

3. Find the least number should be subtracted 9240 to make perfect square.

Elenna [48]

Find the square root of 9240 = √9240 = 96.125... now, take the whole number in the square root of 9240 which is 96 and now square this number so, 96² = 9216. Take the 9216 and subtract it from 9240 which is 24.
