Answer:
cut up the shape
Step-by-step explanation:
if you are looking for area make the 18 yard a triangle so then you have a rectangle and add them together. try this for practice so you can do it on your own next time:)
Given:
The shape is a circle
Radius = 14 cm
To find:
The area and perimeter of the circle
Solution:
The value of π = 3.14
Area of the circle = πr²
= 3.14 × 14²
= 615.44 cm²
The area of the circle is 615.44 cm².
Perimeter of the circle = 2πr
= 2 × 3.14 × 14
= 87.92 cm
The perimeter of the circle is 87.92 cm.
The answer is 14 because 9412/634=14.845
And the closest answer choice is 14.
When we say two angles are complementary, we mean that they add up to a right angle – 90 degrees. Now, we haven’t been given either of the angles directly, but we’ve been given their relationship, and we’ve been given the fact that they’re complementary. If we call the angle’s complement θ, we can express the fact that our angle is 78 degrees less than that with the expression (θ-78). Putting our information together, we have:
θ+(θ-78)=90
2θ-78=90
From there, it’s fairly straightforward algebra; just solve for θ. Remember though, the answer they’re looking for is the (θ-78) term, so make sure to evaluate that once you’ve found θ.
