<h3>
Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
Answer:
-1.555
Step-by-step explanation:
52/(-45)= -1.555555
Answer: 1/25
Step-by-step explanation:
(1/5) * (1/5) = 1/25
Answer:
1526.04
Step-by-step explanation:
the formula for calculating the volume of cone is
V=πr^2(h/3)
Thus,
V = (3.14)(9)^2(18/3)
V = (3.14)(81)(6)
V = 1536.04 yd^3
Rounding off to the nearest tenth, we get
V = 1536 yd^3
