Answer:
Step-by-step explanation:
area of sector = angle/360 * pi * r^2
59.4 = angle/360 * 3.142 * 17.9^2
angle = 21.24
Answer:
Irrational Number
Step-by-step explanation:
So, since it's a right triangle, you can use Pythagorean Theorem to calculate the measure of the hypotenuse.
Pythagorean Theorem says the hypotenuse squared = the sum of the sides squared.
5² + 6² = 25 + 36 = 61
And the square root of 61 is 7.8102496.... and the decimal continues in no distinguishable pattern. Therefore, the length of the hypotenuse is an irrational number.
Answer:
Option d. 1 in: 12 ft.
Step-by-step explanation:
A scale model of building is 2 inches tall. If the building is 24 feet tall then we have to find the scale of the model.
Since scale of the model is represented by the ratio of size of scale model and size of original building
= 
= 
Therefore, Scale of the model is 1 inch : 12 ft.
