Answer:
Neither of them has partitioned the values correctly. The answer to the sum 3568 × 39610 =141 328 480.
They tried the partition method but did not partitioned it correctly.
3568 = 3000+500+60+8
39610 = 30000+9000+600+10
Now multiply each value of 3568 with the values of 39610. Like:
3000 * 30000
3000 * 9000
3000 * 600
3000 * 8
and so on....

Answer:
602.88cm²
Step-by-step explanation:
Find the image of the cylinder attached
Surface area of a cylinder = A=2πrh+2πr²
r is the radius = 4cm
Height h = 20cm
Substitute
A = 2πr(r+h)
A = 2π(4)(4+20)
A = 8π(24)
A = 192π
A = 192(3.14)
A = 602.88cm²
Hence the surface area of the cylinder is 602.88cm²
perimeter = turn of the figure
P = 6 + 3 + 4 + 4 + 3 + 6 + 3 + 4 + 3 = 36
the triangle has 2 équal sides => isosceles
and 1 angle is 60° so the triangle is equilateral
You have to cancel out the variables and then you plug it into a calculator.
