Answer: the shaded region is 1138.97m²

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the larger circle,

Radius = 11.6 + 10.7 = 22.3 m

Area = 3.14 × 22.3² = 1561.4906m²

Considering the smaller circle,

Radius = 11.6 m

Area = 3.14 × 11.6² = 422.5184m²

Area of the shaded region is area of the larger circle - area of the smaller circle. It becomes

1561.4906 - 422.5184 = 1138.97m² rounded up to the nearest hundredth

In the freshman class, 62% of the students take math, 49% take science, and 38% take both science and math. what percentage take

antoniya [11.8K]

we are given

62% of the students take math

so,

$n(M)=62$

49% take science

$n(S)=49$

38% take both science and math

n(M∩S)=38

now, we can use union formula

n(M∪S)=n(M)+n(S) -n(M∩S)

now, we can plug values

and we get

n(M∪S)=62+49 -38

n(M∪S)=73

so,

the percentage takes at least one science or math course is 73%..........Answer

In a triangle, Angle B is twice as large as Angle A. Angle C is five more than

Leona [35]

Answer:

<A = 35 degrees

Step-by-step explanation:

<A = x

<B = 2x

<C = 2x + 5

X + 2x + 2x + 5 = 180 degrees

5x + 5 = 180

5x = 180 -5

x = 175/5

x = 35

Please help me answer 16 please

Answer:

SSS

Step-by-step explanation:

I can identify that these triangles are congruent by using the SSS (Side, Side, Side) postulate theorem. I know this because first, second, and home triangle share the same side as the third, second, and home triangle, meaning they are congruent, so are the other sides of the angle since the question states they are congruent.
