The area of square fabric piece is 10.24 cm^2
Step-by-step explanation:
Square is a four-sided shape where all sides are equal. The area of square is calculated by using its side.
Given
Side length of fabric piece = s = 3.2 cm
The area of square is given by:
Putting s= 3.2
Hence,
The area of square fabric piece is 10.24 cm^2

Answer:
7068.58 yd³
Step-by-step explanation:
A half sphere would use the normal equation for the volume of a sphere and then divide it by two. The first step would be to find the radius of the sphere, which is half the diameter.
d=30 yd
r=d÷2
r = 30 yd÷2
r = 15 yd
Next, we need to use the volume of a sphere equation to find the volume of the full sphere.
V = 4×π×r³÷3
V = 4×π×15 yd³÷3
V = 4×π×3375 yd³÷ 3
V = 13500π yd³ ÷ 3
V = 4500π yd³
Next, we need to find the volume of the dome by dividing by 2.
V = 4500π yd³ ÷ 2
V = 2250π yd³
V = 7068.58 yd³
The total volume of the dome is 7068.58 yd³
Answer:
60g
Step-by-step explanation:
A sample of radioactive element has a mass that weighs 80g
The amount of life spent is two half-lives
This means that after two half lives, the number of daughter materials that would be available in the sample is 60g
Hence 60g of daughter cells would be available after two half lives
