Solve the following problem: 1. The can has a volume of 3165cm³ and a height of 28cm. What is the diameter? 2. This can has a radius of 2ft and a height of 4ft. What is the volume? (Pls answer:) )   Answer: Diameter of can= 12 cm Volume of can= Step-by-step explanation: Assumptions: The can is cylindrical. Formula: Before answering the two problems, we should first identify the formula that will be used. Volume of cylinder: Volume of cylinder in terms of radius: Volume of cylinder in terms of diameter: Another common question is how to find the radius of a cylinder given the volume and height. In order to answer this, the equations above can be derived to find the radius or even the diameter. The derived equations are: Solution for the questions: Number 1: Find the diameter with given volume and height. Use derived equation number 2 above. Given: Volume= 3165 cubic cm and height=28 cm Number 2: Find the volume of the cylinder with given radius and height. Use the volume of ...

Bakit Itinuturing Ni Ibarra Na Pinakamahalagang Hiyas Ng Bayan Ang Mga Pilipina?

Bakit itinuturing ni ibarra na pinakamahalagang hiyas ng bayan ang mga pilipina?   Ang Mga Pilipina Itinuturing ni Ibarra ang mga pilipina na pinakamahalagang hiyas ng bayan sapagkat sila ay tulad ng mga mamahaling bato na maaaring palamuti o ipangganyak sa mga mamahaling gamit na makikita sa mga mamahalin at eksklusibong lugar lamang. Para kay Ibarra, ang mga babae ay dapat na iniingatan sapagkat tulad ng mga hiyas sila ay sensitibo at mahirap mahagilap kaya naman sila ay dapat iniingatan at minamahal. Ang bawat babae ay may likas na katangiang malaki ang maitutulong sa bayan tulad ng pagiging mapag alaga, mapagmahal, malambing, maasikaso, at mapagpasensya. Ang lahat ng kanyang mga ginagawa ay punong puno ng pagmamahal hindi lamang para sa kanyang sarili kundi maging para sa kanyang kapwa. Sa panahon ngayon, ang pagtrato sa mga kababaihan ay hindi na tulad ng pagtrato ni Ibarra sa mga kababaihan. Ngayon ang pagtrato sa mga kababaihan ay depende sa kung paano pinahahalagahan ng is...

The Denominator Of A Fraction Is 7 More Than Its Numerator. If 5 Is Added To Each, The Value Of The Resulting Fraction Is 1/2. Find The Original Fract

Image
The denominator of a fraction is 7 more than its numerator. If 5 is added to each, the value of the resulting fraction is 1/2. Find the original fraction   Answer: The value of the original fraction is 2/9 . Step-by-step explanation: Step 1: Let the denominator be d and the numerator as n. Step 2: Interpret the first statement "The denominator of a fraction is 7 more than its numerator. " denominator = 7 + numerator (since the denominator is more than its numerator) With basis to step 1, the equation one is now: d=7+n Step 3: Interpret the second statement "If 5 is added to each, the value of the resulting fraction is 1/2." To make the interpretation easier then we will use the format of a fraction (numerator/denominator) Add 5 to each: The resulting fraction is equal to 1/2: With basis to step 1, the equation two is now: Step 4: Rearrange equation two in order for it to be in terms of d Step 5: Equate equation 1 and 2 Step 6: Solve for n Step 7: Since we a...
