Answer:
226.22 in^2
Step-by-step explanation:
Given data
Height l= 6in
Diameter= 12in
Radius= 12/2= 6in
The expression for the total surface area of a cone is given as
TSA= πrl+πr^2
substitute
TSA= 3.142*6*6+3.142*6^2
TSA= 113.112+113.112
TSA= 226.22 in^2
Hence the TSA is 226.22 in^2
Answer:
R=19
Step-by-step explanation:
R + 237 = 256
subtract 237 from both sides
R=19
In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:

The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told

Substituting,

Answer: B
Hello :
cot(x) = cos(x)/sin(x) .... cot²(x) = cos²(x)/sin²(x)
1-sin²(x) = cos²(x)
cot²(x)(1-sin²(x)) = ( cos²(x)/sin²(x))× cos²(x) = 1/sin²(x)
Answer:
Length: 64
Width = 21 1/3
Step-by-step explanation:
Width = Length 64 * 1/3 Width
Width = 21.3333333 or 21 1/3
