Answer:

Perimeter is 17.07

Step-by-step explanation:

We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.

We need to use the Pythagorean theorem to get the length of DE.

DE = \sqrt{5^{2} +5^{2}}=\sqrt{50}  = 7.07\\

So the perimeter of DEF is 5 + 5 + 7.07 = 17.07

your friend says that the volume of a sphere with a radius r is four times the volume of a cone with radius r. when is this true
Ierofanga [76]
Volume of a sphere is given by the formula: V_{\circ}=\frac43\pi r^3

If we pull the 4 out front we have, V_{\circ}=4\left(\frac13\pi r^3\right).

Volume of a cone is given by the formula: V_{\triangle}=\frac{1}{3}\pi r^2\cdot h

Notice that if the height of the cone is equal to the radius, V_{\triangle}=\frac13\pi r^2\cdot r

then it's exactly what we see in our volume formula without the 4!

vovikov84 [41]

Answer:

261 km

Step-by-step explanation:

given,s=constant

d1/T1=d2/T2

d1=90km,t1=50 min

d2=? ,t2=(120+25)min

=145min

therefore,d2=(90×145)/50

=261 km
