The answer is 2160. Do you need the steps ?
Answer:
Step-by-step explanation:
Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2
First parallelogram has h=4cm (from first triangle) and a=5.7cm
P2=a*h=22.8cm^2
Big triangle has h=4 and a=5.7+4=9.7
P3=a*h/2=9.7*4/2=19.4
And 4th triangle has the same are lik the first one, P4=8.
P=8+22.8+19.4+8=58.2cm^2
Hello!
Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.
I can see here that this can be divided into a triangle and a rectangle using a horizontal line.
The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.
This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.





Which is in simplest radical form.
Hope this helps!
Answer:
3. 112.2 yd
4. 30m
Step-by-step explanation:
Number 3:
- L × W (length × width) = A
- 18.7 × 6 = 112.2 yd
Number 4:
- B × H (base × height) = A
- 6 × 5 = 30 m
I hope this helps!
Need additional information, which is the height and which is the diameter of the cylinder from the measurements supplied? Standard forumula for locating Radius and Volume of a cylinder are as follows.
Radius=Diameter/2

Volume=Base X height

Base= 3.14*r*r
