The given area of the shape of 57.8·π cm², and length of the slant sides
being a factor of the radius, gives the length of the radius as 3.4 cm.
How can the length of the radius be calculated?Given;
Radius of the two cones are equal.
Slant height of one cone = 2 × Radius
Slant height of the other cone = 3 × Radius
Surface area of the shape = 57.8·π cm²
The curved surface area of a cone = π·r·l
Required:
The radius of the cone.
Solution;
Surface areas of the cones are therefore;
π·r × 2·r, and π·r × 3·r
The total surface area is therefore;
π·r × 2·r + π·r × 3·r = 57.8·π
5·r²·π = 57.8·π
Which gives;
r² = 57.8 ÷ 5 = 11.56
r = √(11.56) = 3.4
The radius of the cones, r = 3.4 cmLearn more about finding the surface area of 3-D shapes here:

In the pattern shown below Day 1 has 4 night eyes,
followed by Day 2 with 8 night eyes, and Day 3 with 16
night eyes, how many eyes will there be on Day 25?
Explain using words or numbers a pattern that you see in
the picture below and write it in complete sentences.
Answer:
The pattern that we know is:
D₁ = 4 night eyes
D₂ = 8 night eyes
D₃ = 16 night eyes
Ok, with these 3 elements we can see that this seems like a geometric sequence.
How we test it? well, the quotient between any pair of consecutive terms must be constant.
D₂/D₁ = 8/4 = 2
D₃/D₂ = 16/8 = 2
Then we can write the n-th term as:
Dₙ = D₁*2^(n-1) = 4*2^(n-1)
Then in day 25, we have n = 25.
Then the term is:
D₂₅ = 4*2^(24) = 67,108,864 night eyes

A rectangle is ____ a rhombus.
A. Always
B. Sometimes
C. Never
Answer:
for a rectangle to be rhombus its sides must be equal. when its satisfied we have square. so a rectangle can be a rhombus only if it has extra properties which would make it a square.
A rectangle is sometimes a rhombus. The correct option is B. Sometimes.
What is a rectangle?A rectangle is a quadrilateral with four right angles, meaning its interior angles measure 90 degrees each. In contrast, a rhombus is a quadrilateral with four sides of equal length, but its angles are not necessarily right angles.
The rectangle is a special type of parallelogram where all angles are right angles. Its properties include having two pairs of parallel sides and diagonals that are equal in length and bisect each other. Rectangles are commonly encountered in everyday life, from the shape of windows and doors to the screens of electronic devices.
Since a rectangle can have equal side lengths, it can also be a rhombus, but only when all four angles measure 90 degrees. Therefore, while a rectangle can be a rhombus under specific conditions, it is not always the case, leading to the answer of "Sometimes."

so I’m just doing this for 5pts
If Arjun adds 20 ml of strawberry syrup in 90 ml milk and his brother adds 45 ml of strawberry syrup in 180 ml milk then Arjun's brother's strawberry milk has a stronger strawberry taste.
What is average?Average is basically sum of numbers divided by how many numbers taken into consideration. It is also known as mean.
How to calculate average?We have been given that Arjun adds 20 ml of strawberry syrup in 90 ml milk and his brother adds 45 ml of strawberry syrup in 180 ml milk. To calculate the strength of strawberry taste we need to find the average syrup added by both the person in milk.
Average of syrup added by Arjun in 1 ml of milk=20/90
=0.22 ml of strawberry syrup.
Average of syrup added by Arjun's brother in 1 ml of milk=45/180
=0.25 ml of milk.
Average of Arjun's brother is greater than average of Arjun.
Hence Arjun's brother's strawberry milk has a stronger strawberry taste than Arjun's milk.
