Answer:
A = 8π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 8 , then r = 8 ÷ 2 = 4
The area of half a circle is then
A =
π × 4² =
× π × 16 = 8π cm²
Answer:
4/5
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A right angled triangle with sides as 3 , 4 and 5 cm .
We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,
sin(β) = p/h
- Where p is perpendicular and h is hypontenuse.
sin(β) = 4/5
<h3>Hence the required answer is 4/5.</h3>
