Circle A has an area of 452.16ft2. With a radius of 12 ft. If circle B has a radius of 17 ft, what is it’s area?
2 answers:
Answer: 907.92 ft²
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:
Where r is the radius of the circle.
2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:

Step-by-step explanation:
We are given that
Equation of curves
Both curves lie on S.
We have to find the equation of tangent plane at P(4,1,4).
Hence, t=0 and u then it satisfied the given point.
Substitute the values in the derivatives
The equation of tangent at point P(4,1,4) is given by
