expand pir^2(9.3-h)

expand

π r^{2} (9.3 - h)

29.21681 \dots r^{2} - π r^{2} h

Solution steps

π r^{2} (9.3 - h)

Apply the distributive law:

a (b - c) = ab - a c

a = π r^{2}, b = 9.3, c = h

= π r^{2} \cdot 9.3 - π r^{2} h

= 9.3 π r^{2} - π r^{2} h

Multiply the numbers:

9.3 \cdot 3.14159 \dots = 29.21681 \dots

= 29.21681 \dots r^{2} - π r^{2} h

(1 + x - 2 x^{2})^{5}

(4 x - 5) e^{x^{2} - 2 x + 1}

(2 x + \frac{y}{4})^{16}

(100 - e^{2}) \cdot 200

- \frac{2 x + h}{x ^{2} ( x + h ) ^{2}}
