Answer:
52.1
Step-by-step explanation:
When dividing decimals, convert the divisor to an integer by moving the decimal point a suitable number of places. Move the decimal point in the dividend the same number of places in the same direction. Make sure the decimal point in the quotient is aligned with the new location of the decimal point in the dividend.
36.47 ÷ 0.7 = 364.7 ÷ 7 = 52.1
Answer: 471.24 square cm.
Step-by-step explanation: First find the area of one circular base by using the formula . The radius is 5, so first square that. 5^2=25. Now multiply by pi, using 3.14 for pi. 25*3.14=78.5.
Since there are 2 circular bases, multiply the area of one base by 2. 78.5*2=157.
Now to find the surface area of the rest of it, first find the circumference of one circular base by using the formula . The diameter is the radius multiplied by 2. 5*2=10. Now multiply by pi. 10*3.14=31.4. Now multiply this by the height of the cylinder. 31.4*10=314.
Finally add up the areas of the two circular bases and the area of the rest of the cylinder. 314+157=471.
Assuming that an expanded form of pi was used by using the π button on a calculator, this answer is closest to 471.24.
