Step-by-step explanation:
Get the square root of 316 which is 17.8
To get surface area you do cross section area x6
17.8×17.8×6=1896
To get volume you do length ×height ×width
17.8×17.8×17.8=5639.752cm³ or 5640cm³ if rounded off
Tan(angle) = Opposite Leg / adjacent leg
tan(37) = x / 10
x = 10 *tan(37)
x = 7.5
Answer:
X = 96
Step-by-step explanation:
This one is pretty simple
So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
so we'd place in those numbers
add the two angles together
than we'd subtract from 180 getting the value of X
Answer: area of shaded region is 141.3 cm²
Step-by-step explanation:
We would assume that the shade region is the area between both circles. The area of the shaded region is the area of the outer circle - the area of the inner circle.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
Radius = 6 cm
Area = 3.14 × 6² = 113.04 cm²
Considering the outer circle,
Radius = 9 cm
Area = 3.14 × 9² = 254.34 cm²
Area of the shaded region is
254.34 - 113.04 = 141.3 cm²
