Answer:
- figure the areas of the rectangle and semicircle
- add them together
Step-by-step explanation:
The area of the rectangle is given by ...
A = LW
A = (20 m)(14 m) = 280 m²
__
The area of the semicircle is ...
A = (1/2)πr²
A = (1/2)π(7 m)² = 24.5π m² ≈ 77 m²
__
Then the total area is ...
280 m² +77 m² = 357 m²
_____
The width of the rectangle is the diameter of the circle, which is twice its radius. The area of a semicircle is 1/2 the area of a circle.
The required measures of the angle are given as,
∠JKL = 72° ∠MLK = 108° ∠JMK = 36°
∠MJL = 54° ∠KNL = 90°
Given that.
The measure of the rhombus is given, we have to determine the measure of the angles,
<h3>What is angle?</h3>
orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as angle.
Here,
∠JKL= 2 × ∠JKM = 72°
∠MLK = 180 - 2 × ∠JKM = 108°
∠JMK = ∠JKM = 36°
∠MJL = ∠MLK/2 = 54°
The diagonal of the rhombus bisect each other at an angle of 90°
So,
∠KNL = 90°
Thus, all the measure of the angles is shown above.

Answer:
The answer to your question is Circumference = 81.64 ft
Step-by-step explanation:
Data
Area of a circle = 530.66 ft²
Circumference = ?
π = 3.14
Process
1.- Calculate the radius of the circle
Area = πr²
-Solve for r²
r² = Area / π
-Substitution
r² = 530.66 / 3.14
-Simplification
r² = 169
-result
r = 13 ft
2.- Calculate the Circumference
Circumference = 2πr
-Substitution
Circumference = 2(3.14)(13)
-Result
Circumference = 81.64 ft
Answer:
the probability to select both marbles to be red is 36% round up to the nearest whole number.
Step-by-step explanation:
11/44 reduces to 1/4
1/4 of the trout caught were tagged.
185 trout were tagged
185 / 1/4 = 740
There are 740 total trout.
