Geometry
The formula for the area of a sector is
Input the things which you already know. (m)
a=πr^2
a=36π
Input this into the equation.
Answer:
Step-by-step explanation:
Convert the mixed numbers above to improper fractions
Rule of basic operation states that when dividing fractions, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that 7/6 becomes 6/7.
Converting the answer above to mixed number result to:
Answer: It is a 90 Clockwise Degree Turn.
Step-by-step explanation:
From my knowledge, a 90-degree turn is a turn to the right.
So if you turn the "C" in the Y-axis 90 degrees you will get The "C" on the X-axis.
For Example: When you walk around a street you either turn 90 degree's to the right or 90-degrees to the left.
Hope this Helps!
Answer:
2 and 3 look similar to A
1, 4, 5 and 6 are not similar to A .
hopefully you got it right.
Answer:
1. Use the Adjacent and opposite side (Ignore the Hypotenuse)
Or use HERO'S FORMULA based on the information given
2. Area = 216cm^2
Step-by-step explanation:
There are three to four ways we can go about finding the area of a triangle. And a these would be dependent on the information given about the triangle.
From the question, you said the three side lengths are given. In such case, we employ the HERO FORMULA.
HERO FORMULA:
Area = √ s(s-a)(s-b)(s-c)
where s = 1/2(a + b + c)
a, b, c are the three sides
But since the question insisted that we use 1/2* base * height. Let's use our know of right angle to dissolve that.
A right angle triangle has three sides. The longest is always the Hypotenuse.
Let's take it this way.
Hypotenuse = 30cm
Opposite= 18cm
Adjacent = 24cm
Area = 1/2 * base * height
Area = 1/2 * 18 * 24
Area = 1/2 * 432
Area = 216cm^2
We ignored the longest side, (the Hypotenuse)
