Answer:
surface area of cylinder= 2πrh + 2πr²
2×22/7×1×8+2×22/7×1×1
<u>352</u><u>.</u> + <u>4</u><u>4</u>
7. 7
= 50.3 + 6.25
= 56.55cm²
Answer:
6/8, 9/12, 12/16 etc.
Step-by-step explanation:
You just think of a number for an example 2. Multiply 3 and 4 by it and you have a fraction equivalent to 3/4.
Hope this helped
If you are multiplying fractions it doesn't matter if there are different denominators because you multiply straight across.

Answer:
Step-by-step explanation:
Perpendicular height will split the base into two equal parts.
Use Pythagorean theorem,
hypotenuse² = base² + altitude²
= 28² + 45²
= 784 + 2025
= 2809
hypotenuse = √2809 = √53 * 53 = 53 mm
Perimeter = 53 + 53 + 56 = 162mm
