Answer:
25π/4 square meters
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius of the circle.
The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...
A = π(5/2 m)² = (25/4)π m²
The area of the circle is 25π/4 square meters.
__
As a decimal, that is 6.25π square meters.
Answer:
(3+4)2=14. That is how to put it in bracket
The answer is 6.
EXPLANATION
All you have to do is to distribute the exponent outside of the parentheses to the constant inside.
That is,
From the equilateral (60-60-60) triangle with all legs of length 1, we can view half the triangle, forming a 30-60-90 triangle, with the hypotenuse measuring 1, the short leg1/2<span>, and the long leg 3 2. Therefore, we have sin 30° = </span>1/2<span>, cos 30° = 3 2, sin 60° = 3 2 and cos 60° = </span>1/2<span>.
