First, we need to find the difference of the two, which is 4715-3809=906. After that, we need to figure out what percentage that if of 3809, which is rounded to 0.24 or 24%.
The surface area of the solid shape is the amount of space on it
The radius of the two cones is 2.93 cm
<h3>How to determine the radius?</h3>
The given parameters are:
- Cone 1: slant height, l = 2r
- Cone 2: slant height, L = 3r
- Surface area = 135. 21 cm²
The surface area of the shape is calculated using:
T = πr(L + l)
So, we have:
135.21 = πr(2r + 3r)
Evaluate
135.21 = 5πr²
Divide both sides by 5π
r² = 135.21/5π
Evaluate the quotient
r² = 8.61
Take the square root of both sides
r = 2.93
Hence, the radius of the cones is 2.93 cm

Answer:
1/5
Step-by-step explanation:
For Monday
The fraction of homework Chain completed =
40% of her homework
= 40% = 40/100
= 2/5
For Tuesday
The amount of home work left =
= 1 - 2/5
3/5
The fraction of homework Chain completed on Tuesday = 2/3
= 2/3 Of 3/5
= 2/3 × 3/5
= 2/5
Let the total complete homework be represented by 1
Hence:
The Fractional part of her homework left for her to complete after Tuesday =
1 - (2/5 + 2/5)
Lowest common denominator is 5
= 1 - (2 + 2/5)
= 1 - (4 /5)
= 1/5
40% = 32/x
Rewrite using a decimal
.40 = 32 / x
Multiply both sides by x
.40x = 32
Divide both sides by .40
x = 32 / .40
x = 80
Write the full fraction
32/80
Answer 32/80
