The sides of an equilateral triangle are increasing at the 2cm per sec.Find the rate at which the area increases when the side is 10cm. |
|
Answer» Side of equilateral ∆ = 10cm. AREA of equilateral ∆ = √3 a^2 /4 sq.units. Area of first ∆ = √3 10^2/4 sq. Cm. = 25√3 sq. Cm. Side INCREASED by 2 cm. New side=12cm. Area of second ∆ = √3 12^2 /4 sq. cm. = 36√3 sq. Cm. Increase in area = 36√3 - 25√3=11√3sq.cm.per second Rate of increase in area (% in increase) = 11√3 X 100 / 25√3 = 44% per second |

✨✨ Hello Friends. Please Answer This Question ✨✨➡️ Find the least perfect square number exactly divisible by 8, 15, 20, 25. |
|
Answer» To FIND this we need to find the LCM of 8, 15, 20 and 25 which is 1800 Prime factorisation of 1800 is 2*2*2*3*3*5*5 We see that 2 is not in a pair. So 1800 is not a PERFECT square so we need to multiply it by 2 to obtain the answer. 1800*2 = 3600 3600 is the answer. Please mark my answer as the brainliest. |
