Given - a cone with volume 769?3 ft³ , having a height of 15 ft

To calculate - radius of the cone

We know that ,

$\bold{Volume \: of \: cone = \frac{1}{3}\pi \: r {}^{2} h }\\$

substituting the values in the formula stated above ,

$\bold{769.3 = \frac{1}{3} \times 3.14 \times r {}^{2} \times 15} \\ \\\bold{\implies r {}^{2} = \frac{769.3 \times 3}{3.14 \times 15} } \\ \\\bold{\implies r {}^{2} = \cancel\frac{2307.9}{47.1}} \\ \\\bold{ \implies \: r {}^{2} = 49} \\ \\ \bold{\implies \: r = 7 \: ft}$

therefore ,

radius = 7 cm

Multiply the exponent of x by 4giving The answer is x^4 evaluates to Multiply and 5 Multiply and 1 The just gets copied along. The answer is 5*x^4 evaluates to Multiply the exponent of x by 4giving The answer is x^4 evaluates to Multiply and 6 Multiply and 1 The just gets copied along. The answer is 6*x^4 evaluates to Multiply the exponent of x by 2giving The answer is x^2 evaluates to Multiply and 3 Multiply and 1 The just gets copied along. The answer is 3*x^2 evaluates to 6*x^4-3*x^2 evaluates to The answer is 6*x^4-3*x^2+7 evaluates to Multiply by we multiply by each term in term by term. This is the distributive property of multiplication. Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and 7 Multiply and 1 The just gets copied along. The answer is × 7 = 5*x^4*(6*x^4-3*x^2+7) evaluates to The final answer is
