Answer:

208 cm^2

Step-by-step explanation:

We can find the area of the net by adding up the area of each of the 6 rectangles that make up the net. Since two of each rectangle are the same, we only have to find the area of the 3 different sized rectangles and multiply each by 2.

Rectangle pairs are:

  • Left rectangle and right rectangle
  • Top rectangle and the rectangle above the bottom rectangle
  • Bottom rectangle and the rectangle surrounded by all for sides

Now, let's solve the question.

Left rectangle:

6 x 4 = 24, rectangle has area of 24 squared cm

Top rectangle:

6 x 8 = 48, rectangle has area of 48 squared cm

Bottom rectangle:

4 x 8 = 32, rectangle has area of 32 squared cm

Add up the areas:

(24 x 2) + (48 x 2) + (32 x 2) = 208

The rectangle has a surface area of 208 squared cm

What is the volume of a small cone if:
Amiraneli [1.4K]

Answer:

Volume of smaller cone =301.44

Step-by-step explanation:

First let angle of cone be\alpha.

then sin(\alpha ) = 3/5       (For bigger triangle)

Same cone angle is for smaller one because they are similar.

cos(\alpha ) = 4/5

Now for smaller cone radius be R

3/5 =R/Slant height

Slant height =5/3R

Lateral surface area =\frac{1}{2}R^{2}\beta  [R = slant height]  

Given lateral surface area =60\pi =\frac{1}{2}(\frac{5R}{3} )^{2} \beta   ...................................1

2\pi R=\frac{5R}{3}\beta        ................................................2

\beta=\frac{6\pi }{5}

Put angle beta in equation 1 and find the value of R

R =6 cm

Height =\frac{4R}{3}

Thus volume =\frac{1}{3}\pi6^{2}*8

                     =301.44
