Answer:

The formula of the volume of a cylinder is known as follow

Where

π is 3,14 or 22/7.

d (diameter) is a straight line segment that crosses a center and connects two points on the circle.

r is the radius of the to part of the cylinder.

h is the height.

we can subsitute to our formula knowing that

d = 4cm (turn to r = 2cm,because the formula use r) ; h = 11cm

V = πr²h

= 3,14 × 2² × 11

= 3,14 × 4 × 11

= 3,14 × 44

= 138,16 rounded off (138,2cm3) result

Varvara68 [4.7K]

Mean of data = sum of values ÷ number of data

We have three values; 84, 87, and $x$

Sum of values = $84+87+x$ = $171+x$

We want the value of $x$ to give mean between 85 and 90 inclusive

$85 \leq \frac{171+x}{3} \leq 90$
$85*3 \leq 171+x \leq 90*3$
$255 \leq 171+x \leq 270$
$255-171 \leq x \leq 270-171$
$84 \leq x \leq 99$

Hence, the value of $x$ is between 84 and 99 inclusive
