There are 4 semicircles, each radius is 8cm, so we get the total areas of these semicircles: 4×0.5×
π
and the square area: 16²
so the total area of figure: 16²+4×0.5×
π=256+128π
Answer:
25868.61 ft squared.
Step-by-step explanation:
First, find the area of the circle. Area equals pi times the value of the radius squared. Because there is only three quarters of the circle there, you need to divide the area by 4, and then multiply it by 3.
Then, for the rectangle, multiply the two numbers together to get the area. Just copy my answer, and you'll be fine.
Answer:
x = 16
Step-by-step explanation:
The two marked angles are supplementary:
(7x -2) +(4x +6) = 180
11x +4 = 180
11x = 176
x = 176/11 = 16
The value of x is 16.

<em>Additional comment</em>
The angle on the left is 110°; the one on the right is 70°, so that answer checks.
These marked angles are called "consecutive exterior" angles. Just as "consecutive interior" angles are supplementary, so are consecutive exterior angles.
Essentially, all of the obtuse angles are congruent, as are all of the acute angles. The obtuse angles are supplementary to the acute angles.
Answer:
11800
Step-by-step explanation:
Answer:
<h2>- 417</h2>
Step-by-step explanation:
n - integer
The sum of n and 181 is equal to -236:
n + 181 = -236 <em>subtract 181 from both sides</em>
n + 181 - 181 = -236 - 181
n = -417
