80% bc 20/25 equals 4/5 and 4/5 equals x/100 and when you do that math it equals 80%
Answer:
£3.25
Step-by-step explanation:
You would add £1.25 and £00.50 which is £1.75 then you would do £5.00-£1.75 which is £3.25
Answer:
142.1π in³
Step-by-step explanation:
Given that:
The radius (r) = 7 in
The slant height (y) = 25 in
Then the height (x) can be determined by using the Pythagoras rule:
y² = x² + r²
25² = x² + 7²
125 = x² + 49
125 - 49 = x²
x² = 76
x = √76
x = 8.7
The formula for the volume of a cone is;
= 1/3 πr²h
where;
height(h) is calculated as "x" from above = 8.7
Then;
= 1/3 × π × (7 in)² × 8.7 in
= 142.1π in³
