Answer:
18.02 cm
Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.
Remember, because we know the length and width, we know the two sides.
10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
The answer is c
12.4 feet by 9.5 feet
Answer:
Your teacher is correct.
Step-by-step explanation:
So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.
With this information in mind, we can create the expression:
2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)
Now simply the equation:
6x + 48 = 180
6x = 132
6x/6 = 132/6
x = 22
Angle C = 44
Angle B = 88
Answer:
Based off of the calculations I did, I got 32 as the answer.
Step-by-step explanation:
Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.
So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.
10/6 * 19 = 31.666...
Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.
31.666... + 4/12 = 32.
Thus, Jason used 32 cans of paint in total.
