you can split the figure in multiple parts to make it easier:
area rect. 1;
9m×4m= 36m²
area rect 2:
7m×3m= 21m²
area tri.:
18m× (4m+7m+4m-5m)
=18m× 10m
=180m²
total area:
36m²+21m²+180m²= 237m²
Answer:
V = 523.6 yd³
Step-by-step explanation:
The equation for the volume of a sphere of radius r is
V = (4/3)πr³
and if we substitute 5 yds for r, we get
V = (4/3)*π*(5 yd)³, or
V = (4/3)·π·125 yd³, or approxomately
V = 523.6 yd³
First, find the area of the circle as a whole. Then find the percentage or fraction of that area.
STEP ONE
As you probably know, you use this formula to find the area of any circle.
We know what the radius is, so substitute the 4 for the r in the formula.
Simplify.
STEP TWO
Now that we know what the area of the circle is as a whole, let's find the fraction of that area. We want to the know the area of the shaded part.
Multiply the area by 3/4.
So, the answer is the first option.
Answer: I know that the answer is 47.
Step-by-step explanation: add up all the angles to get 180 degrees.
