The volume of two sphere are640 cm3and 240 cm3 ? Find the ratio of theirdiameters? |
Answer» Given :
To find :
Concept :To calculate the radius of their diameters, FIRSTLY calculate the radius of the two spheres. Multiply the radius by 2, the resultant value will be the DIAMETER of the sphere. Now, after dividinh both the diameters the resultant value which we'll get will be the ratio of the diameter of both the spheres. Formula of volume of sphere :-
where,
Formula to calculate diameter :-
Solution :Radius of the first sphere :- → Volume of the sphere = 4/3 πr³ Substituting the given VALUES, → 640 = 4/3 × 22/7 × r³ → 640 = 88/21 × r³ → TRANSPOSING 88/21 to the left hand side. While transpoing the denominator will change into numerator and the numerator will change into denominator. → 640 × 21/88 = r³ → 320 × 21/44 = r³ → 160 × 21/22 = r³ → 80 × 21/11 = r³ → 1680/11 = r³ → 152.73 = r³ → Taking cube root on both the sides. → 5.35 = r
Diameter of the first sphere :- → Diameter = 2 × Radius Substitute the given value, → Diameter = 2 × 5.35 → Diameter = 10.7
Radius of the second sphere :- → Volume of the second sphere = 4/3 πr³ Substituting the given values, → 240 = 4/3 × 22/7 × r³ → 240 = 88/21 = r³ → Transpoing 88/21 to the other side. → 240 × 21/88 = r³ → 120 × 21/44 = r³ → 60 × 21/22 = r³ → 30 × 21/11 = r³ → 57.27 = r³ → Taking cube root on both the sides. → 3.85 = r
Diameter of the second sphere :- → Diameter = 2 × Radius Substitute the given value, → Diameter = 2 × 3.85 → Diameter = 7.7
Ratio of the diameter of the two spheres :-
→ Ratio = 10.7 ÷ 7.7 → Ratio = 1.39 Therefore,

Answer» Given : Three slogans were finalized and the number of banners made for each slogan is in A.P. the total number of banners made is 90 and their product is 5130, To find : the no. of banners for each type of slogan. (a) 7, 50, 33 (b) 3, 30, 57 (c) 5, 53, 32 (d) 7, 50, 30 Solution: let say number of banners are a - d , a , a + d Sum = a - d + a + a + d = 3a = 90 => a = 30 Hence banners are (30 - d) , 30 , (30 + d) Product is 5130 => (30 - d)(30) (30 + d) = 5130 => 900 - d² = 171 => d² = 729 => d = 27 30 - d = 30 - 27 = 3 30 + d = 30 + 27 = 57 hence numbers are 3 , 30 , 57 Learn More: Find the sum of frist 51 terms of the AP WHOSE 2nd term is 2 and 4th ... the 9TH and 19th terms of a series of a.p are respectively 35 and 75 ... |

Sonia had a recurring deposit account in a bank and deposited $600 per month for2 1/2years. If the rate of interest was 10% p.a., find the maturity value of this account.(2018) |
|
Answer» Given, Principal (P) = $600 Time (in months) = (2*12)+6 months = 30 months (n) Rate of Interest (R) = 10 % p.a. S.I = [P*n(n+1)/24*R/100] = [600*(30*31)/24*10/100] = [600*930/24*0.1] = [600*38.75*0.1] = $2325 Maturity Value = (Principal*n)+S.I = (600*30)+2325 = 18000+2325 = $20325 The Maturity Value will be $20325.
