Hi 3DST3!
The diameter of a circle is x 2 the radius. The radius is, as you checked, 5m. Therefore the answer cannot be A.
The circumference formulas are
* diameter or 2 (3.14 rounded)r. The radius of the circle is 5 and pi (rounded) = 3.14, therefore, 2*3.14*5. 2*3.14*5 = 31.4. Therefore b isn't a correct answer choice and neither is e.
The diameter, as I said, is 2 * r. Our r is 5. 2 * 5 = 10. 10 is our diameter and C the correct answer choice.
The area of a circle's formula is
Therefore 3.14 * 5^2 -> 3.14 * 25 = 78.5. D is correct.
Answers that are correct:
C
D
F
Answers that are incorrect:
A
B
E

The length of EF in the given triangle is 8.80 m.
Step-by-step explanation:
Step 1:
In the given triangle, the opposite side's length is 16.2 m, the adjacent side's length is x m while the triangle's hypotenuse measures 16.2 m units.
The angle given is 90°, this makes the triangle a right-angled triangle.
So first we calculate the angle of E and use that to find x.
Step 2:
As we have the values of the length of the opposite side and the hypotenuse, we can calculate the sine of the angle to determine the value of the angle of E.
So the angle E of the triangle DEF is 57.087°.
Step 3:
As we have the values of the angle and the hypotenuse, we can calculate the cos of the angle to determine x.
Rounding this off to the nearest hundredth, we get x = 8.80 m.
Answer is QM = 18
You can find the length of QM by using Pythagorean theorem. See the attachment.
It is a quadrilateral with 4 equal congruent sides.
If SP = 30, so do the other 3 sides indicated by the tick marks on all 4 sides.
We will call side RQ = the hypotenuse
or side “c” = 30
We know RM is leg “b” = 24
Side “a” is our unknown QM
Our formula is
a^2 + b^2 = c^2
a^2 + 24^2 = 30^2
a^2 + 576 = 900
a^2 = 900 - 576
a^2 = 324
Take square root of both sides to solve a
a = 18
QM = 18
