The volume of a cylinder varies jointly with the square of the radius and the height. If the volume of a cylinder is 50.265 cubi

Evgesh-ka [11]

Answer:

197.92 in³

Step-by-step explanation:

$\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

Given:

r = 3 in
h = 7 in

Substituting the given values into the formula:

$\begin{aligned} \implies \textsf{Volume of a cylinder} & =\sf \pi (3)^2(7)\\ & = \sf 63 \pi\\ & = \sf 197.92\:in^3\:(nearest\:hundredth)\end{aligned}$

Estimate the area of the circle. Use 3.14 or 22/7 for π.<br> explain pls and Thank you

Aleks04 [339]

Answer: 616 cm^2

Step-by-Step Explanation:

Diameter = 28 cm
Radius (r) = 28/2 = 14 cm
Area = πr^2

Therefore,
= πr^2
= π * r^2
= 22/7 * 14 * 14
= 22 * 2 * 14
= 616

Area = 616 cm^2
