The answer is the third answer choice.
Answer:
28.26
Step-by-step explanation:
To find the area of a circle you take pi times the radius squared ()
And to find the radius you divide the diameter by two.
Answer:
Step-by-step explanation:
20) the angle at the base of the right angle triangle is alternate to the given angle. Since alternate angles are equal, it means that the base angle of the right angle triangle is 27 degrees.
To determine x, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 27 = x/580
x = 580Sin27
x = 580 × 0.454
x = 263.3 to the nearest tenth.
21) the angle at the base of the right angle triangle is alternate to the given angle. Since alternate angles are equal, it means that the base angle of the right angle triangle is 18 degrees.
To determine x, we would apply
the Tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan 18 = x/2
x = 2tan18
x = 2 × 0.3249
x = 0.6 to the nearest tenth.
Answer:
50 berries left over
Step-by-step explanation:
55 berries 1700 berries
--------------- = -------------------
1 jar x jars
Using cross products
55x = 1700*1
Divide each side by 55
55x/55 = 1700/55
x = 1700/55
Changing to a mixed number
55 goes into 1700 30 times
30 *55 =16501700-1650 = 50
x = 30 50/55 = 30 10/11
There are 50 berries left over
Answer:
47.7 square units
Step-by-step explanation:
The area of triangle ABC with two given sides and an inclusive angle =
1/2absinC
Where : a = 8, b = 12, C = 84
Area of Triangle ABC = 1/2 × 8 × 12 × sin 84
Area of Triangle ABC = 47.737050978 square units
Approximately to the nearest tenth = 47.7 square units.
