Answer:
4 cm radius
- Volume = 267
- Surface area = 201
___
Square root 3
- Volume = 22
- Surface area = 38
Step-by-step explanation:
4/3 * 3.14 * r^3 is formula. For this, I am going to use 3.14 for pi.
Since r = 4, r ^3 = 64.
Now we do 64 * 3.14 * 4/3 = ~ 267.
Now let's do the surface area.
4 * 3.14 * r^2 is the formula. For this, I am going to use 3.14 for pi.
Since r = 4, r ^ 2 = 16.
4 * 16 * 3.14 = ~ 201
______
Now, let's do Square root of three.
3 square root of 3(i cubed it) * 4/3 * 3.14 = ~ 22
For surface area it is 3 * 4 * 3.14 = ~ 38.
:) This took a while xD
Answer:
4 feet and 2 inches
Step-by-step explanation:
5 feet and 6 inces= 66 inches
66-16=50
50= 4 feet and 2 inches
Answer:
Step-by-step explanation:
A) identical triangles PSR and PSQ
B) in the given triangle PQR angle P is 90 degrees and PS is perpendicular on QR. so the angle PSR and angle PSQ is 90 degrees also angles RPS , SPQ are 45 degrees . hence when two angles of a triangle are 90 and 45 degrees. the third is also 45 degrees. when the three angles of two triangles are equal they are said to be similar
C) the triangle PSR is a isosceles triangle therfore the two sides of the two oposite equal angles must be equal. if RS=4 then SP=4 as well the sides opposite to 45 degrees angles. the third side can be found by using the formula
c²=a²+b²
c²=4²+4²=16+16=32
c=√32=√16*2=4√2
