Determine the area of the composite figure below

Mathematics
1 answer:
MrRa [10]2 years ago
5 0

Answer:

  • 2772 cm²

Step-by-step explanation:

<u>Work:</u>

  • 2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
  • => π x 21 x 21 + (π x 42 x 42/4) = Area of figure
  • => (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
  • => 2(22/7 x 21 x 21)
  • => 2(22 x 3 x 21)
  • => 2772 cm²

Hence, the area of the shape is 2772 cm².

The shape is a rectangle, will you please help me find the angle measures of 1,2 and 3?
Ulleksa [173]

Answer:

  ∠1 = ∠3 = 54°; ∠2 = 36°

Step-by-step explanation:

Each of the triangles is isosceles. Triangles opposite each other are congruent, so ∠2 is congruent to 36°.

∠2 and ∠3 are complementary, so ∠3 is 54°. Since ∠3 is congruent to ∠1, it, too, is 54°.

Could somebody please answer these four questions with simple yet explanatory answers?
Kamila [148]
1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10  <--width+width
4+4=8 <---length + length 
10+8=18  <--total perimeter
18 * 9=162in^2  <--multiplied the height +perimeter of base  
Lateral Area=162in^2

2) Same concept as the previous one
 Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2

Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2

Stanley, the skunk, is traveling from point A to point B by taking a shortcut through the pond.A path that avoids the pond is 25
san4es73 [151]
Stanley the skunk will save about 15.5 feet.

This problem can be solve with the Pythagorean Theorem. The possible paths that Stanley can take make a right triangle. The legs of the triangle are 25 and 28, and the hypotenuse would be 37.5.

If Stanley went the long way, he would travel 25 + 28 = 53 feet. Taking the short way (hypotenuse) is 53 - 37.5 = 15.5 feet shorter.
