Answer:
r = 7.33 units
Step-by-step explanation:
Given that,
A cylinder has a radius of r units, and that the height of the cylinder is also r units.
The lateral area of the cylinder is 338 square units.
We need to find the value of r.
The formula for the lateral area of the cylinder is given by :
![A=2\pi rh](https://tex.z-dn.net/?f=A%3D2%5Cpi%20rh)
Put all the values,
![2\pi r^2=338\\\\r=\sqrt{\dfrac{338}{2\pi}} \\\\r=7.33\ unit](https://tex.z-dn.net/?f=2%5Cpi%20r%5E2%3D338%5C%5C%5C%5Cr%3D%5Csqrt%7B%5Cdfrac%7B338%7D%7B2%5Cpi%7D%7D%20%5C%5C%5C%5Cr%3D7.33%5C%20unit)
So, the value of r is equal to 7.33 units.

Distribute the exponent to each term, then move your negative exponents to the opposite side then simplify.
Answer:
1
Step-by-step explanation:
(f+g)(1) = f(1) +g(1) = -1 + 2 = 1
__
The pair (1, -1) in the definition of f tells you f(1) = -1.
The pair (1, 2) in the definition of g tells you g(1) = 2.

... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction
_____
In the real world, it seems probable that Samantha will be offered the choice of using the coupon <em>or</em> the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.
The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.
