Answer:
Step-by-step explanation:
Area = 84sqaure inch
Width = 2 1/2inch = 5/2inch
Area = l × width
So: 84 = l × 5/2
168 = 5l
l =>168/5
l = 33 3/5
3 length 4 height @ ten base I got it wrong so plz dont mind the answer don't even put it on your homework
Answer: the answer is: 60π in²
Step-by-step explanation:
Lateral surface area for a circular cone is given by the formula in the attached picture.
Lateral Surface Area,
=πr √( r² + h²)
=π (6) √( 6² + 8²)
= π6 √( 36 + 64)
= 6π √(100)
= 6π (10)
= 60π in²

Answer:
Step-by-step explanation:
The length of the polar coordinates ray is found using the Pythagorean Theorem: ray length = √( (-1)^2 + (-2)^2 ) = √( 1 + 4) = √5
Because both the x- and the y-coordinates here are negative, the ray is in Quadrant III. Measuring the angle counterclockwise from 0°, we get
Ф = 180° + arctan 2/1, or Ф = 180° + 63.43°, or 243.43°
The desired polar coordinates are (2√2, 243.43°)
