Find the area for these 2 shapes (b& c)

The first shape is a right triangle composed with a semi circle.

The right triangle has a height of 50cm, and its base is the diameter of the circle, which is twice the radius, which is 30cm.

So, the area of the triangle is

The area of the circle is simply

So, the area of the shape is

The second shape is the difference between an outer circle and an inner one. The area is thus the difference of the two areas: let be the outer radius and be the inner one. The area of the shape is

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
