Answer:

6524.51 ft^2

Step-by-step explanation:

The surface area of a cylinder is given as;

SA = 2\pi rh + 2\pi r^2

where r = radius

h = height

The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:

40 / 2 = 20 feet

The surface area is therefore:

SA = (2*\pi* 20 * 32) + (2*\pi *20^2)\\\\SA = 4021.24 + 2513.27\\\\SA = 6524.51 ft^2

The surface area of the cylinder is 6524.51 ft^2.

Write the equation of the circle centered at (0,1) with radius 15.
NNADVOKAT [17]

Answer:

x^2+(y-1)^2=225

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

(h,k)=(0,1)\\r=15\ units

substitute

(x-0)^2+(y-1)^2=15^2

x^2+(y-1)^2=225

Jon caught four fish that weighed a total of 252 pounds. The kingfish weighed twice as much as the amberjack and the white marli
Allushta [10]

Answer:

  • amberjack, 21 lbs
  • kingfish, 42 lbs
  • white marlin, 84 lbs
  • tarpon, 105 lbs

Step-by-step explanation:

Let k, a, m, t represent the weights of the kingfish, amberjack, marlin, and tarpon, respectively. The problem statement tells us ...

  • k = 2a
  • m = 2k
  • t = 5a
  • k + a + m + t = 252

Using substitution, we can rewrite the last equation as ...

... (2a) + (a) + 2(2a) + (5a) = 252

... 12a = 252 . . . . . collect terms

... a = 21 . . . . . . . . .divide by 12

Then k = 2a = 42; m = 2k = 84; t = 5a = 105.
