AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Llana [10]

Formula for the volume of cone is $\frac{1}{3} \pi r^2h$

Where r= radius of the cone

h = height of the cone

The value of pi is 3.14

Given volume of larger cone is 131 cm^3

Volume of larger cone = $\frac{1}{3} \pi r^2h$

131 = $\frac{1}{3} \pi 5^2h$

Solve for h

131 = 26.1667 *h

So h= 5 cm

The height of bigger cone = 5cm

Now we find the volume of smaller cone

Two cones similar so the sides are in proportional

$\frac{radius(small)}{radius(large)}= \frac{height(small)}{height(large)}$

$\frac{2}{5} =\frac{ height of small}{5}$

Height of smaller cone = 2cm

volume of smaller cone = $\frac{1}{3} \pi 2^2*2$

= 8.38cm^3

Mr. Claussen needs a total of 15 pounds of ground beef to make hamburgers for a company picnic. He finds that 2 pounds of ground

Marat540 [252]

Answer: $33.00

Step-by-step explanation:

Given

Mr. Claussen needs 15 Pounds of ground beef

It is stated that 2 pounds of beef cost $4.40

Using unitary method

1 Pound cost $\frac{4.4}{2}=\$2.2$

For 15 pounds it is

$\Rightarrow 15\times 2.2=\$33$

Thus, he has to spend $33 for 15 pound meat

Answer:

A. The area is $78.54m^2$

B. She needs to cover 1661.9 square feet of tiles for the base of the swimming pool

Step-by-step explanation:

Question A:

Let us assume that the leash is pegged to the ground using a stake. as a result, the dog can move around the stake. The path that the motion of the dog would trace is a circle, and the radius of the circle will be the length of the leash.

Since we know this, we can easily find the area of the circle using $\pi r^2$

Area of the circle = $\pi \times 5 \times 5 = 78.54m^2$

Question B

Dulce wants to cover the whole surface area of the floor of the circular swimming pool with tiles.

We already know that the swimming pool is circular, hence, the surface area of the base of the swimming pool will be the same as the area of a circle, with the same radius.

The area of the circle can be calculated using $\pi r^2$

Area of circle = $\pi \times 23 \times 23 = 1661.9ft^2$
