Answer:
0.35
Step-by-step explanation:
I hope its right!!!
- use sin (opp/hyp)
- Plug in values so: sin45=x/2
- Switch the sin45 and x place, they are "equal" in a sense
- Simplify in calculator
Answer:
1661.06 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 11.5 cm
Size of synthetic leather needed =?
To know how many square centimetres of synthetic leather needed to cover the ball, we shall determine the area of the ball. This can be obtained as follow:
Radius (r) = 11.5 cm
Pi (π) = 3.14
Area of ball =?
The shape of a ball is spherical in nature. Thus, we shall apply the formula for calculating the area of a sphere. This is illustrated below:
A = 4πr²
A = 4 × 3.14 × 11.5²
A = 4× 3.14 × 132.25
A = 1661.06 cm²
Thus, 1661.06 cm² of synthetic leather needed to cover the ball.
Answer:
In 1812, with President Madison in office, Congress declared war against the British. The war began with an attack on Canada, both as an effort to gain land and to cut off British supply lines to Tecumseh's Indian confederation, which had long troubled the US. ... The US troops were badly routed.
Step-by-step explanation:
The length of the radius of the cylinder is 2 units.
The lateral surface area of a cylinder = <span>
2πrh</span>
where, r = base radius
h = height of cylinder
Now, height of cylinder = 2r units
⇒ 16 π = 2×π×r×<span>h
</span>⇒ 16 π = 2×π×r×2r
⇒
= 4
⇒ r = 2 units
Thus, radius is 2 units.
The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
