I NEED HELP I DONT UNDERSTAND​
Vikki [24]

Answer:

answers are given below

Step-by-step explanation:

1.

Circumference = 2\pi r

Where 2r = Diameter

Hence

Circumference =  \pi \times Diameter

2.

No there is no such circle in which relationship between Radius and Diameter can be represented without  \pi.

This is because while deriving the relation the angle measurement ts taken into consideration and the angle are measured in radians i.e. in terms of  \pi not degrees.

3. We can not determine the exact circumference because  \frac{22}{7} is a rational number and but its value is approximately taken from  \pi and  \pi is an irrational number

MAKE YOU THE BRAINLIEST EASY QUESTION Show the formula for finding the area of a triangle. Then find the area of a right triangl
lesya692 [45]

Answer:

Formula to find the area of a triangle is 1/2(bxh). The area of the right triangle is 28.

Step-by-step explanation:

To solve this problem you would plug in the base and height into the formula and follow the order of operations (P.E.M.D.A.S). So the equation would then read 1/2(5x11.2). Once you solve inside the parenthesis, the equation then reads, 1/2(56). Then you solve what half of 56 is, which is 28.


I hoped this helped you!
