Answer: Hello there!
we want to know the square root of 98 rounded to the nearest tenth
first, we have that:
And now we need to round it to the nearest tenth.
the nearest tenth is the first number after the decimal point, and in this case is an 8, and you can see that the next number is a 9, when we are rounding, if the next number is 5 or bigger, then we round up (the 8 transforms into a 9) if the next number is less than 5, then we don't round up.
Then in this case we have:

Answer:
V = 1206.3
Step-by-step explanation:
This shape is made up of a cylinder on the bottom and a cone on the top. We'll find the volumes of these shapes separately and then add them together.
Volume of a cylinder = area (of the base) x height
Substitute in the formula for the area of a circle.
V(cylinder) = x h
Substitute in the values for the radius (8) and height (4)
V(cylinder) = x
x 4
Evaluate using a calculator
V(cylinder) = 804.2477
To the nearest tenth, V(cylinder) = 804.2
Volume of a cone = . This is the area of the circular part of the cone (
), multiplied by the height from the point to the base, all divided by 3.
Substitute in the values for the radius of the circle (8) and the height (6)
V(cone) = (On the top it's
x
x 6)
Evaluate using a calculator
V(cone) = 402.1239
To the nearest tenth, V(cone) = 402.1
Total volume = V(cylinder) + V(cone)
= 804.2 + 402.1
= 1206.3
