7. A cone has a volume of 942 cubic inches

Harman [31]

Answer:

Step-by-step explanation:

V of a cone V=3.14* r^2*h/3

942=3.14*r^2*9/3

r^2=942/(3.14*3)=100

r=sqrt100=10

Secant BE and CF intersect at point A inside D. What is the measure of BF?

svet-max [94.6K]

Answer:

$\text{BF}=80^{\circ}$

Step-by-step explanation:

We have been given a circle D. Secant BE and CF intersect at point A inside D. We are asked to find the measure of arc BF.

We know that when two secants intersect inside a circle, then the measure of angle formed is half the sum of intercepting arcs.

$m\angle EAF=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}$

$70^{\circ}=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}$

$2*70^{\circ}=\frac{\text{Measure of arc EF+Measure of arc BC}}{2}*2$

$140^{\circ}=\text{Measure of arc EF+Measure of arc BC}$

We know that degree measure of circumference of circle is 360 degrees, so we can set an equation as:

$\text{Arc EF+BC+EC+BF}=360^{\circ}$

$140^{\circ}+140^{\circ}+\text{BF}=360^{\circ}$

$280^{\circ}+\text{BF}=360^{\circ}$

$280^{\circ}-280^{\circ}+\text{BF}=360^{\circ}-280^{\circ}$

$\text{BF}=80^{\circ}$

Therefore, the measure of arc BF is 80 degrees.
