Answer:
C.) 418 cm²
I hope this helped you : )
Step-by-step explanation:
First, you find the area of the square:
19 cm x 19 cm = 361 cm
Next, you find the area of the triangle:
(19 cm x 6 cm) ÷2 =57 cm
Last, you add the two:
361 cm + 57 cm = 418 cm²
Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.
If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!
Answer:
a) Prepare a frequency table for the data
Step-by-step explanation:
Answer:
A = 0.785m²
B = 31400cm²
C = 7850cm²
D = 785,000mm²
Step-by-step explanation:
To solve this question, we'll have to find the area of a circle which is
Area of a circle = πr²
1. The diameter of the circle = 1m
Area of a circle = πr²
r = radius of the circle
π = 3.14
Radius = diameter / 2
Radius = 1 / 2 = 0.5m
Area = 3.14 × (0.5)²
Area = 3.14 × 0.25
Area = 0.785m²
2. Radius = 100cm
Area of a circle = πr²
Area = 3.14 × (100)²
Area = 3.14 × 10000
Area = 31400cm²
3. Diameter = 100cm
Area = πr²
Radius = diameter / 2
Radius = 100 / 2
Radius = 50cm
Area = πr²
Area = 3.14 × (50)²
Area = 3.14 × 2500
Area = 7850cm²
4. Radius = 500mm
Area = πr²
Area = 3.14 × (500)²
Area = 3.14 × 250,000
Area = 785,000mm²
