Distance equals rt solve for t?
T = Distance/R
S plus r equals h solve for h?
Congratulations! You already have. h = S+r
How do you solve for the Radius r in the cylinder equation V equals rh?
If v = r * h then> r = v / h
What is the equation for a quarter circle?
x = r*cos(theta) y = r*sin(theta) for alpha < theta < alpha + 90 degrees where r is the radius and alpha is any angle (which determines the direction in which the quarter circle is facing).
What is the radius of the area 345cm2?
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
How do you solve for x and y in an angle?
If X and Y are sides of a right triangle, R is the hypoteneuse, and theta is the angle at the X-R vertex, then sin(theta) is Y / R and cosine(theta) is X / R. It follows, then, that X is R cosine(theta) and Y is R sin(theta)
X squared plus y squared equals 2y.change into polar equation?
x2+y2=2y into polar coordinates When converting Cartesian coordinates to polar coordinates, three standard converstion factors must be memorized: r2=x2+y2 r*cos(theta)=x r*sin(theta)=y From these conversions, you can easily get the above Cartesian equation into polar coordinates: r2=2rsin(theta), which reduces down (by dividing out 1 r on both sides) to: r=2sin(theta)
Sketch a polar curve for r equals sin theta?
It will be a circle.
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
What is the formula for the area of a partial circle?
www.mathwords.com about mathwords website feedback Segment of a Circle A part of the interior of a circle bounded by a chord and an arc. 1/2 x R(squared) x ((pi x theta/180) - sin theta) In which R is the circle radius and theta is the angle ( in degrees) which is subtended by the chord (which together with the arc form the boundaries of the partial circle. Note that a value of theta of 180 degrees leads to pi (R squared)/2, or one half the area of a circle.
What is r squared-r-56 factored?
r2-r-56 factored out equals (r-8)(r+7).
What is r if r squared equals s?
Square root of s, or negative square root of s.
V equals pi r squared h?
Formula for the volume of a cylinder.
How do you transfer spherical coordinate into cartesian and vice versa?
If spherical coords are r and theta, then x = r*cos(theta) and y = r*sin(theta) Conversely, r = sqrt(x2 + y2) and theta = arctan(y/x) provided x is not zero. and theta = 90 deg when x = 0
What does the equation R squared equals 5E-05 mean?
Written in equation form is: R2 = 5E-5. 5E-5 expressed in decimal form is 0.00005. if you wanted to solve for R, take the square root of 5E-5, which is 0.0070710678.
Where is the area vector for a sphere?
R^2sin(theta)d(theta)d(phi)(r-hat)
Equation for radius of a circular motion?
The equation for the radius of circular motion is given by ( r = \frac{{v^2}}{g \cdot \tan(\theta)} ), where ( r ) is the radius of motion, ( v ) is the velocity of the object, ( g ) is the acceleration due to gravity, and ( \theta ) is the angle of bank of the incline.
