Answer:

360 cm^2.

Step-by-step explanation:

Area of the base = 10*10 = 100 cm^2.

We find the slant height of the sides using Pythagoras:

h = sqrt ( 12^2 + 5^2)

h = sqrt 169

h = 13.

Area of the triangular sides = 4 * 1/2 * 10* 13

= 260 cm^2

So the total surface area = 100 + 260

= 360 cm^2.

A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 8 inches. Find the volume of the bowl. Use 3.14 for pi

gayaneshka [121]

Answer: 267.947 (or 267.95) inches^3

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3}\pi r^{3}$ .

To find your radius (r), divide the diameter of 8 inches by 2. The radius is 4 inches.

Plug in your numbers to the volume equation to get $\frac{4}{3} (3.14)(4^3)$ . The first step is to cube 4 (4*4*4) to get 64. Now your equation is $\frac{4}{3}(3.14)(64)$ .
