Answer:
TSA=115.5cm²
Step-by-step explanation:
T.S.A=3πr²
Given r=3.5cm
eq.
3×22/7×3.5×3.5
=3×22×0.5×3.5
=115.5cm²
Answer:
1306.90≅ 1307 rounded to the nearest tens
Step-by-step explanation:
r= radius = 13 cm
l is the slant height =19 cm
surface area of the cone= area of the circle + area of the curved of the cone
SA=πrl +πr²
SA=π(13)(19) +169π
SA= 247π +169π= 416π=1306.90≅ 1307 rounded to the nearest tens
Only the dividend is stated. there's no divisor
The factor of this expression is 67. Hope this helps! =)

Explanation:</h2>
See the figure below for a better understanding of the problem. Since we have a 45-45-90 triangle, this is an isosceles triangle, so both the adjacent and opposite sides measure the same value, say, x. Then the hypotenuse would be:

Then. the ratio of the length of the hypotenuse to the length of a side is:
