Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
Answer:
SAS Similarity
Step-by-step explanation:
ΔOPQ similar to ΔRST
∠Q = ∠T
OQ : RT = 28 : 84 = 1 : 3
QP : TS = 16 : 48 = 1 : 3
The measures of two sides of ΔOPQ are proportional to the measure of two side of ΔRST and their included angles are congruent. The triangles are similar by SAS Similarity.
Multiply 3 by 2 then multiply the product by 10= 60 minutes or 1 hour
The equation will have only one solution. The value of x is -5.
<h3>What is an equation?</h3>
An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given equation x + 10 = 5 will be solved as below:-
x + 10 = 5
Take 10 to the right of the equation.
x = 5 - 10
x = -5
The equation is giving the value of x equal to -5. Then the equation will have only one solution.
Therefore, the equation will have only one solution. The value of x is -5.
