What is the length of the hypotenuse of the triangle?

√ 20 cm
√ 23 cm
√ 40 cm
√ 58 cm

√58 cm.

Step-by-step explanation:

The hypotenuse is the line AB.

Using the Pythagoras theorem:

AB^2 = 3^2 + 7^2

AB^2 = 9 + 49 = 58

AB = √58 cm.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:
