Step-by-step explanation:

The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width

Answers

Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

A=320^2!
Length x width = area

What is the distance between points A(-3,4) and B(1,-2)? Round to the nearest 10th if necessary.

A. 6.08
B. 6.1
C. 6.5
D. 7.2

Answers

Answer:

D. 7.2

Step-by-step explanation:

6^2 +4^2 = c^2

sqrt 36 + sqrt 16 = c^2

c^2 = sqrt 52 = 7.21110255 = 7.2

Answer:

Step-by-step explanation:

Distance between two points is given by

|xy|=√(x2-x1)² +(y2-y1)²

So putting the points A(-3,4) B(1,-2) into the equation

|AB|= √(4--3)²+(-2-1)²

=√(7)²+(-3)²

= √49+9

= √58

=7.2

The volume of the below cylinder is _________________ ft3

Answers

Answer: 4082 or 4084.07

Step-by-step explanation:

formula = πr^2h

(if you use 3.14 for pi) = 3.14 x 10^2 x 13 = 4082

(normal pi) = pi x 10^2 x 13 = 4084.07044967 (4084.07 rounded to the nearest hundredth)

Answer:

V=1300π ft

Step-by-step explanation:

The formula for the volume of a cylinder is V=πr^2h, so you need to find the correct values so you can plug them in. The radius is diameter divided by 2, (diameter being the line across the circle,) and the diameter is 20ft, so the radius is 10ft. Now you can plug the values into the formula, getting V=π10^2(13). Square 10 to get V=π100(13), then multiply 100 by 13 to get V=π1300. Since you want the exact value, the answer is 1300π ft.
