9. Vu needs to buy mulch for the garden with the dimensions shown in the figure. For how mulch area does Vu need to buy mulch?
the circle is 5.5 yd

the circle one

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:
