Question

find the volume of this sphere. use 3.14 for π. a sphere with radius 2.5 cm. volume of a sphere v = (4/3)πr³. v =? cm³. round your answer to the nearest tenth.

Explanation:

Step1: Identify given values

Radius $r = 2.5$ cm, $\pi = 3.14$

Step2: Calculate $r^3$

$r^3 = 2.5^3 = 15.625$

Step3: Substitute into volume formula

$V = \frac{4}{3} \times 3.14 \times 15.625$

Step4: Compute intermediate product

$\frac{4}{3} \times 3.14 = \frac{12.56}{3} \approx 4.1867$

Step5: Calculate final volume

$V \approx 4.1867 \times 15.625 \approx 65.4$

Answer:

$65.4$ cm³
