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
Answer: 1 and one fourths because 1/4 times 5 is 1 1/4
Step-by-step explanation:
So what u would do is 8 times 6 and ur answer is 48 I believe
3/12 or 1/4 is left of the bread
2*4
-----= 8/12 - i did this for a common denominator
3*4
8 1 9
--- + --- = --- i did this to find the total eaten
12 12 12
12 9 3 1
--- _ --- = --- or simplified as ----
12 12 12 4
the total amount of bread left is 3/12 or 1/4 (simplified)
