Let's use the ratio 3:6 as an example. So 3:6 is the same as 3 over 6, aka 3/6. Divide 3 by 6 and you'd get 0.50. To turn a decimal into a percent, move the decimal to the left 2 times. (If you want to turn a percent into a decimal, you'd move the decimal to the right 2 times.) So then, 0.50 becomes 50%. Hope I helped!!! :-) (You could also multiply the decimal by 100 if you find that quicker/easier)
This is incorrect the answer would be 6
Answer:
2√10
Step-by-step explanation:
Given the following data;
Area of square = 40
Mathematically, the area of a square is calculated by using the formula;
Area, A = s²
Where;
s is the length of sides of a square.
Substituting into the formula, we have;
40 = s²
s = √40
s = √4 * √10
s = 2 * √10
s = 2√10
Answer:
25.13 cm³
Step-by-step explanation:
Volume of a cone or pyramid is:
V = ⅓ A h
where A is the area of the base and h is the height.
V = ⅓ π r² h
V = ⅓ π (2 cm)² (6 cm)
V = 8π cm³
V ≈ 25.13 cm³
